Whether the modern demand for flowers has created the supply, or the supply has found an appreciative public, we need not stay to discuss. The fact remains that the last four or five decades have witnessed a phenomenal extension in the use of flowers by all classes of the community, for the decoration of the house no less than for beautifying the garden. Primarily, this advance of refinement in the popular taste is traceable to the skill and enthusiastic devotion of the florists who have supported in all their integrity the true canons of floral perfection, and whose labours will continue to be imperative for maintaining the standards of quality. By their severe rules of criticism the florists further the ends of floriculture subjectively, and by the actual results of their labours they render objective aid, their finest flowers serving not only as types, but as the actual stud for perpetuating each race. Hence the decline of floriculture would imply the deterioration of flowers, and the prosperity of floriculture involves progress not only in those subjects which lie within the florists’ domain, but of many others to which they have not devoted special attention. Yet the acknowledgment must be made that, brilliant as their triumphs have been, the methods they practised have in some instances entailed very severe penalties. Continuous propagation for many generations, under artificial conditions, so debilitated the constitution of Hollyhocks, Verbenas, and some other subjects, that the plants became victims of diseases which at one time threatened their existence. To save them from annihilation it was necessary to desert the worn path of propagation, and raise plants possessing the initial vigour of seedlings. In stamina these seedlings proved eminently satisfactory, although in other respects they were at first sadly disappointing. It then became clear that before show flowers could be obtained from seedlings judgment and skill must be devoted to the art of saving seed. This was necessarily a work of time, demanding great patience and rare scientific knowledge. The task was undertaken with enthusiasm in many directions, and the results have more than justified this labour of love. Formerly, the universal mode of perpetuating named Hollyhocks was by the troublesome process of cuttings, or by grafting buds on roots of seedlings in houses heated to tropical temperature. In many places it was the custom to lift the old plants, pot them, and keep them through the winter in pits. All this was found requisite to insure fine flowers. While the burden of the work was thus rendered heavy, the constitution of the plant became enfeebled, and at one time the fear was entertained that its extinction was at hand. But the new system has preserved the Hollyhock, and at the same time afforded a striking example of the principle that seed saved scientifically is found to reproduce the varieties it was taken from. Seedling Hollyhocks now give double flowers of the finest quality; and the seedling plants are less liable to disease. So with the Verbena. From suitable seed plants can be raised that will produce the most resplendent flowers, and instead of propagating a stock to keep over winter, to be stricken with mildew and cost no end of care, only to become diseased at last, a pinch of seed is sown in January or February, and soon there is a stock of healthy plants possessing the vigour peculiar to seedlings. These, being bedded out at a proper time, flower far more freely than plants from cuttings, and produce trusses twice the size.
To illustrate the change of method still further we may instance the Cineraria. Formerly this was a troublesome plant to grow, because it was considered necessary to propagate named varieties by divisions and suckers. The restricted system was reflected in limited cultivation. Few were willing to venture on a task known to be hedged about with difficulties. By degrees it was discovered that the finest Cinerarias might be secured by simply sowing seed, and giving the plants the usual cultivation of tender annuals. This has brought the Cineraria within the reach of thousands who would not attempt to grow it under the old system, and the consequent gain to society is immense.
What has been done with the Cineraria has its parallel in quite a number of the most elegant decorative flowers. Brilliant results have been achieved with Begonias, Calceolarias, Cyclamens, Gloxinias, Primulas, and Schizanthus. It has also ceased to be needful to keep such large stocks of bedding and other plants through the winter, for Ageratums, Lobelias, and Pansies have proved amenable to the new treatment, and very much of the accustomed labour in striking and potting cuttings, as well as the expense of glass, fuel, and the frequent purchase of high-priced plants, have been rendered unnecessary. Even among the flowers which are properly designated annuals, new and delightful variations have been obtained from original types. Of these we have examples in Aster, Godetia, Larkspur, Mignonette, Phlox Drummondii, Poppy, Stock, Sweet Pea, and many others. In some instances the increase in the size of the flowers is remarkable, and in others the development of new tints will surprise those who are not familiar with the labours of modern hybridisers.
Thus a revolution has been accomplished in the economy and complexion of the English Flower Garden, a revolution which has reduced and simplified the gardener’s labours, augmented the number and enhanced the beauty of many flowers, effected a marked saving in the cost of garden pleasures, and brought the culture of a large number of the most attractive subjects within the means of those who had neither the facilities nor the knowledge requisite for pursuing the florist’s methods. There appear to be no limits to further progress. All that we can do is to experiment and gather knowledge, and those who love gardening may assist in extending the area of this new and cheap system of producing some of the most elegant garden flowers in one season from seed alone.
The time and the method of sowing flower seeds must in each case be regulated by considerations as to their nature. Seeds of tender plants are usually sown in pots or pans and placed on a moderate hot-bed or in a propagating house early in spring, and in this case the plants have greenhouse cultivation until the time arrives for hardening them off preparatory to final planting. But seeds of many hardy flowers may be treated in the same way, when a long season of growth is necessary for their development. Thus Phloxes, Verbenas, and Hollyhocks, plants that differ immensely in habit and constitution, may all be sown in February, and put side by side in the same warm pit or vinery, or even in the warmest corner of any greenhouse, and the very same treatment will suit them equally well. The soil should be principally loam and sand, with a little old thoroughly well-rotted manure from a hot-bed or compost heap; and light, air, and moisture must be regulated with a view to insure a free and vigorous growth from the first, with the least possible amount of artificial heat. In some cases, however, the sowing should be deferred to March or April, and the result will be far more satisfactory than the growth made under the stimulus of artificial heat earlier in the season. But in every case the plants must have sufficient time; for although the rapid system has been developed, the constitution of the plants remains unchanged, and those which have heretofore been classed as biennials and perennials need a long season when treated as annuals.
A considerable proportion of the finest flowers may be raised from seed by the aid of a frame and a little careful management. We will take as an example a very restricted garden. Here is a small frame and some packets of seed, and the month of February or March has arrived. The pans and pots are made ready with sweet sandy compost, and the seeds are sown and labelled, and the pans and pots are packed together in the frame on a bed of clean coal ashes, or some slates, or tiles, or bricks laid on the soil, to promote warmth and cleanliness and to prevent the intrusion of worms among the seeds. By simple management almost as quick a growth of seeds can be insured in this frame as with the aid of a hot-bed, and the secret consists in careful storage of the heat of the sun. Lay over the seed-pans sheets of glass to prevent evaporation, and let the sun shine full upon them. Be careful as to moisture: they must never be wet, never dry, and the water must not be slopped about carelessly. It is a good rule to immerse the pots or pans in a vessel containing soft water, slightly tepid. When the seedlings begin to appear, give a little air and lay sheets of paper tenderly over them during the hour or two at midday when the sun may be shining brightly. But keep them from the first as ‘hard’ as possible with plenty of light and air, always taking care that they are neither roasted, nor blown away by the cruel east wind, nor nipped at night by a killing frost. A few old mats or light loppings of trees laid over the frame from sundown to sunrise will be sufficient protection at those trying times; and when spring frosts are making havoc with the tender sprouting leaf and bloom in every part of the garden those little things will be safe under their glass cover, and slight experience will show that a common frame may become a miniature hot-house in the hands of one who has learned to make failure the stepping-stone to success. We must not omit to mention that the owner of such a garden, or, indeed, of any garden, will be prudent to take advantage of the first fine weather to sow in the open ground whatever flower or vegetable seeds should be sown at that season. The frame garden can be reserved, if needful, for wet weather, because it is of the utmost importance to sow a good breadth of seeds in the open ground as early as possible in the month of March.
Turning from this small example to the great garden, it will be obvious that to those who always have heavy work on hand the advantages of this transference, of labour from the old system to the new are immense. Both to employers and gardeners the advantages are of importance; the propagation of bedders by cuttings, and of florists’ flowers by suckers and divisions and layers and pipings, will not, of course, be completely abolished; but for all ordinary purposes the ends in view may be accomplished more simply, more expeditiously, and more cheaply than heretofore. The pits hitherto appropriated to bedders, and the like, may to a great extent be liberated, and there will be no difficulty in finding for them more profitable occupants. While Mushrooms and early Potatoes and winter salads are in request, it will be a gain to many a garden to have reduced the summer display of flowers to a simple system of seed-sowing, at an expense that may be described as merely nominal.
Before dealing specifically with certain flowers, it may be advisable to say a few words generally concerning the culture of Annuals—Hardy, Half-hardy, and Tender—and also on hardy Biennials and Perennials.
Annuals.—Although the most popular kinds of annuals are largely employed in the embellishment of flower gardens, they are adapted for many uses to which they may with advantage be more frequently applied. A few misconceptions prevail as to the relative merits of this class of plants. By some they are regarded as ‘weedy’ and ‘short-lived.’ Their very cheapness, and the relatively small amount of skill required in their cultivation, tend in some degree to detract from their value in public estimation. We will not be so rash as to say that a more extended use of annuals would render unnecessary the cultivation of what are especially known as ‘bedding plants’; but there is something to be said on behalf of annuals that may be worth the consideration of all who are interested in the development of freshness, variety, and richness of colour in the flower garden. In the first place, these plants come into flower within a comparatively short period of time from the sowing of the seed, and it is a matter of considerable importance that a large proportion of the best continue beautiful until the very close of the season. Sometimes in the autumn Geraniums become literally washed out, while Tom Thumb Nasturtiums may be ablaze with colour, and continue so when the Geraniums are housed for the winter. A large number of showy and long-lasting annuals are adapted for employment in bedding, and by a little management those that do not last the season out may be replaced by others for succession; thus affording the advantage of increased variety, and making no demand for glass and fuel to keep them through the winter as do the ordinary bedders. We have had great and glorious sheets of Candytufts, snow-white, rich crimson, and bright carmine; and when they began to wane they were removed, and the ground planted with Asters, and very soon there was another display, so fresh and bright and various that no greenhouse bedders could surpass them. Great hungry banks, that would have swallowed many pounds’ worth of greenhouse plants to cover them, have been made delightfully gay at a very trifling cost by sowing upon them Tropæolums, Tom Thumb Nasturtiums, Bartonia aurea, the dwarf varieties of Lupinus, Virginian Stock, Collinsia bicolor, Convolvuluses, Candytufts, Eschscholtzias, Poppies, and Clarkias; and damp, half-shady borders have been delicately tessellated by means of Forget-me-nots, Venus’ Looking-glass, Pansies, the Rosy Oxalis, Nemophilas, Godetias, Silenes, Coreopsis, and Scabious.
For the more important positions in the flower garden we have choice of many really sumptuous subjects, such as Stocks, Asters, Balsams, Drummond’s Phlox, Lobelias, the lovely new varieties of Antirrhinums, Dianthus, Portulacas, Zinnias, tall Stock-flowered Larkspurs, Nemesias, and many other flowers equally beautiful and lasting. We do not hope by these brief remarks to change the prevailing fashion—indeed, we have no particular wish that way—but we feel bound to observe that it is sufficient for the beauty of the garden that the greenhouse bedders should be confined to the parterre proper. It is waste of space and opportunity to place them in the borders everywhere, as is too commonly done. In sunny borders, annual and perennial herbaceous plants are far more appropriate.
Some time since, while walking over a large garden, we left the rich colouring of the geometric beds to discover what should make the wondrous glow of crimson on a border far away; and to our surprise it proved to be a clump of the Indian Pink, which had been sown as an annual with other annuals, and was there shining in the midst of a constellation of the loveliest flowers of all forms and hues, the result simply of sowing a few packets of seed. No one can despise the Wallflower in the spring, and the heavenly-blue flowers of Nemophila insignis in early summer will tempt many a one to walk in the garden who would care little for sheets of scarlet and yellow that in full sunshine make the eyes ache to look upon them. It must be remembered, too, that among annuals are found many most richly-scented flowers; others, like the everlastings and the grasses, are valuable to dry for winter use for employment in bouquets, and garlands in Christmas decorations; and the Sweet Peas, and Tropæolum canariense, and climbing Convolvulus may be employed to cover arbours and trellises with the best effect possible, and may even be allowed to hang in festoons about the sunny parts of rockeries, or trail over the ground to make genuine bedding effects. Another important matter must have mention here, and we commend it to the consideration of gardeners who are severely taxed to secure extensive displays of flowers during the summer season. It is that a number of plants of highly ornamental character, usually treated as perennials, are really more effective, besides occasioning less labour to produce them, when cultivated as annuals. The Dianthus and its several splendid varieties do better as annuals than biennials. For all the ordinary purposes of display, Lobelias may be as well grown from seed as from cuttings, and in every garden will be found proof of the small amount of care they require; for we find stray, self-sown plants in pots of Geraniums and other places, and these, if left alone, become perfect bushes, and are a mass of flowers all the summer. Many annuals commonly reputed to be tender and usually raised in heat do very well indeed on a more rough and ready method. In proof of this, sow Perilla nankinensis in the first week of May where it is required, and in the month of July you will probably be convinced that Perilla does not always need careful nursing in heated houses through the spring. Even the really tender Castor-oil Plant will thrive if sown in the open ground the first week in May. Having no check, as plants put out from pots must have, the growth will be regular and sturdy, and attain magnificent dimensions.
Perhaps the most effective way of growing annuals is to arrange them in harmonious blendings or contrasts of colour. The wide choice of varieties available admits of an almost endless number of combinations, and the following tables, classified according to colour, will no doubt afford some serviceable suggestions, although these by no means exhaust the list. The height is indicated in feet and Climbers as ‘Cl.’

Yet one other method of growing annuals calls for special mention. It is not fully recognised that a number of subjects, usually associated only with beds and borders, may also be flowered with the greatest ease under glass in winter and early spring. Those who have not hitherto attempted the culture of annuals in this way will be delighted with the charming effects produced. Among the subjects most suitable for the purpose are Alonsoa; the Star and Dunnettii varieties of Annual Chrysanthemum; Clarkia elegans; Dimorphotheca; Gypsophila elegans; Linaria; Nemesia Suttoni; Nicotiana, Miniature White and N. affinis; Phlox, Purity, one of the most lovely pot plants for the conservatory and of especial value for decorative work at Easter; Salpiglossis; and the pretty blue, Cineraria-like, Swan River Daisy. From the fact that these annuals are of the hardy or half-hardy types it will be readily understood that no great amount of heat is required to bring them to maturity; indeed, the more hardy the treatment the better for their well-doing. Seed should be sown during August or September in pots or pans placed in a cool frame, the seedlings being pricked off into other pots as soon as they have attained a suitable size. As colder weather approaches, transfer to the greenhouse or conservatory, and provided the night temperature is not allowed to fall below 45° all should be well. During the day give the plants the maximum of air whenever weather permits.
Hardy Annuals.—The seeds should be sown on a carefully prepared surface from which large stones have been removed, and the clods must be broken, but the soil should not be made so smooth as to become pasty under rain. Sow thinly, in rows spaced to agree with the height of the plant, cover with a very slight coat of fine dry earth—the smallest seeds needing but a mere dusting to cover them—and, from the first, keep the plants thinned sufficiently to prevent overcrowding. Spring-sown annuals are worthy of a better soil than they usually have allotted them, and also of more careful treatment. It is not wise to sow earlier than March or later than the middle of April. In the after-culture the most important matter is to keep the clumps well thinned. Not only will the bloom of crowded plants be comparatively poor and brief, but by early and bold thinning the plants will become so robust, and cover such large spaces of ground with their ample leafage and well-developed flowers, as really to astonish people who think they know all about annuals, and who may have ventured after much ill-treatment to designate them ‘fugacious and weedy.’ Although the sowing of hardy annuals direct on to beds and borders where the plants are wanted is economical in labour and avoids the check which transplanting occasions, the practice of raising annuals on specially prepared seed-beds and pricking out the plants to blooming quarters is sometimes followed. The soil into which they are transferred for flowering should be deeply dug, thoroughly broken up, and, if at all poor, liberally manured. It is an excellent plan also to sow hardy annuals outdoors in autumn, but it is needless to say more on this subject here, as it is dealt with fully at page 313.
Half-hardy Annuals.—Give these as long a period of growth as possible to insure a vigorous plant before the season of flowering. The best time for sowing is February, or the beginning of March; for although some kinds may with advantage be sown earlier, it is safer, as a rule, to wait for sunshine and full daylight, so as to keep up a steady and continuous growth. The soil for the seed-pans should be rich and fine. Good loam, improved by the addition of thoroughly decayed manure and leaf-mould, with sufficient sand to render the texture porous, will suit all kinds of annuals that are sown in pans under glass. Sow the seed thinly, cover very slightly, and lay squares of glass over to keep a uniform degree of moisture without the necessity of watering. Should watering become necessary, take care to avoid washing the seeds out. If the pans or pots are stood in a vessel containing several inches depth of water until sufficient has been absorbed, there will be no occasion to pour water on the surface. A gentle heat is to be preferred; when germination is too rapid it tends to the production of weak plants. As soon as the young plants appear, remove the glasses and place the seed-pans in the fullest light, where air can be given without danger to them. A dry east wind blowing fiercely over them will prove a blast of death. If they have no air at all, they will be puny, rickety things, scarcely worth planting out. Choice varieties should be carefully pricked out into pans and pots as soon as large enough; this will promote a fine, stocky growth and a splendid development of flowers. Take care not to plant out until the weather is favourable, for any great check will undo all your work, and make starvelings of your nurslings. If you cannot command heat for half-hardy annuals, sow in the first week in April, put the pans in a frame facing south, and the seeds will soon grow and do well. If that is too much trouble, sow in the open border early in May, making the border rich and friable, that they may have a good chance from the first.
Tender Annuals.—These require the same general treatment as advised for half-hardy annuals. But it is desirable to sow in a stronger heat than is necessary for annuals that are to be planted out. It is also requisite to be in good time in pricking out the seedlings, for if they get much drawn they cannot make robust pot plants. A light, rich, perfectly sweet soil, containing a fair proportion of sharp sand, is necessary to insure plants worth having. It is also important to get them into separate small pots as soon as possible, and to shift them on to larger and larger pots, until they have sufficient pot room for flowering, after which shift no more. As soon as these pots are filled with roots, give very weak manure water constantly until the plants are in flower, and then discontinue it, using instead pure soft water only.
Hardy Biennials and Perennials.—These are often sown in pans or boxes, and are pricked off when large enough into other pans or pots before they are transferred to beds or borders. The system has certain advantages in insuring safety from vermin and proper attention, for it is an unfortunate fact that too many cultivators consider it needless to thin or transplant sowings made in beds or borders. The plants are frequently allowed to struggle for existence, and the result is feeble attenuated specimens which, with trifling care and attention, might have become robust and capable of producing a bountiful bloom in their season. Still, it should be clearly understood that all the hardy biennials and perennials may be grown to perfection by sowing on a suitable seed-bed in the open ground, protecting the spot from marauders of all kinds, and by early and fearless thinning or transplanting. As a rule, we advocate one shift before placing the plants in final positions.
ABUTILON
Half-hardy greenhouse perennial
Handsome plants, two feet or more in height, can be produced from seed and flowered in a single season. They are useful for training to greenhouse walls, and they may also be transferred to open borders for the summer. When employed for the latter purpose, the plants should be lifted and put into pots about the end of August, after there has been a penetrating shower. In the absence of rain a soaking of water on the previous day will prevent the soil from falling away from the roots.
February and March are the right months for sowing seed, and for the pots any fairly light compost will answer. Prick off the seedlings when about an inch high, putting the plants in down to the seed-leaves. They must never be allowed to suffer for want of water, nor should they be starved in small pots. The growth had better not be hurried at any stage; the plants will then develop into shapely specimens with very little care.
ACHIMENES
Greenhouse or stove perennials
Although Achimenes can be propagated by division of the tubers, the simpler method of raising a supply from seed has become a common practice. During March or April sow in pots or pans, and while quite small transfer the seedlings to separate pots. It is important to insure free drainage, especially as frequent watering is a necessity while the plants are in active growth. Achimenes are generally kept in a high temperature; but they do not really need so much heat as Gloxinias, and in a warm greenhouse they can be flowered without the least difficulty. This is one of the finest subjects for growing in hanging-baskets.
ALONSOA
These popular half-hardy flowers are not only valuable for a summer display in borders, but they make charming subjects for the conservatory in the spring months. For blooming outdoors seed may be sown in pans in March and the plants treated in the manner usual for half-hardy annuals, or a sowing can be made in the open towards the end of April. Plants for flowering indoors in April and May should be raised from seed sown in the preceding August and September. Grow on the seedlings steadily in pots, but do not force them in any way. In fact, the treatment should be as nearly hardy as possible, a night temperature of 45° being generally sufficient to carry them through the winter.
AMARYLLIS
Hippeastrum
The majority of the named varieties are expensive, and a very considerable saving is effected by raising plants from seed. Thanks to the skill of the hybridiser, the seedlings not only compare favourably with flowers grown from costly bulbs, but they have been successful in winning certificates and awards of merit.
The germination is so irregular that it is well to put only one seed in each small pot. The most suitable soil is a mixture of two parts loam and one of leaf-mould, with sufficient coarse grit to insure free drainage. The proper temperature is about 65°. After the seedlings are established follow the treatment advised on page 340.
ANEMONE
The Windflower. Hardy perennial
The discovery that it is easy to flower the popular St. Brigid and similar Anemones from seed in about seven months from the date of sowing has given a great impetus to the culture of this plant, especially as it possesses a high value for decorating vases, in addition to its usefulness in beds and borders. From seed sown in February or March the plants should begin to bloom in September or October of the same year, and continue to flower until the following June, when it is unprofitable to retain them longer. No coddling of any kind is necessary. Dig a trench in a sheltered, sunny spot, and fill it with rich soil freely mingled with decayed cow-manure. If the land happens to be somewhat tenacious, Anemones will take kindly to it, but it should be well worked, and it may be needful to add a little fine sandy compost at the top as a preparation for the seed. The woolly seed should be rubbed with sand, and the two may be sown together thinly in lines. As a finish the ground should be lightly beaten with the back of a spade. Germination is decidedly slow, so that until the seedlings appear the removal of weeds requires care. The plants should be thinned until they stand six inches apart. Seed may also be sown in June or July for plants to flower in the following year, and the results will probably be even more satisfactory than from the spring sowing.
ANTIRRHINUM
Snapdragon. Hardy perennial
In bygone years Antirrhinums were seldom seen beyond the limits of old-fashioned cottage gardens. But even then the Snapdragon was a popular flower, and it was generally perpetuated by subdivision of the plants. Now, in common with a large number of perennials and biennials, the Antirrhinum is almost exclusively grown from seed. This altered method of culture has resulted in a marked advance in the size and colour of the spikes of bloom, and has also increased the vigour and floriferous character of the plants. In the process of raising, selecting and re-selecting the stocks, experts have found it possible to develop three distinct classes—Tall, Intermediate, and Dwarf—so that the value of the plant as an ornament in the garden has been advanced beyond the dreams of a former generation of gardeners. The Tall varieties attain a height of about three feet; the Intermediates generally range between twelve and eighteen inches, and the Dwarf or Tom Thumb section seldom exceeds six inches. All three classes have a distinct value for different positions in the garden.
Antirrhinums are not fastidious as to soil and may be relied on to give satisfaction in almost any spot chosen for them. Still, it must be admitted that they are conspicuously successful on dry soils and in sunny positions. This will account for the surprising displays occasionally seen on old walls and in large wild rockeries, where they are perfectly at home, apparently indifferent to the starving conditions in which their lot is cast.
The fact that the plant possesses such sturdy independence of character greatly enhances its value and usefulness. Nothing more handsome can be imagined in a border than the gigantic spikes of the Tall varieties, and they make a magnificent decoration for vases at a season when flowers suitable for cutting are much needed. The Intermediate Antirrhinums, like the Tall class, combine advantages for both bedding purposes and for cutting, perhaps in a still greater degree. The varieties are so numerous and charming that an enthusiast has suggested the desirability of devoting a garden to Antirrhinums alone. Although the Tom Thumb section is also frequently employed for bedding, these dwarf-growing varieties are better adapted for ribbon borders, or as an edging to carriage drives.
Antirrhinums may be grown as half-hardy annuals or as perennials, but the former is the simplest course for obtaining plants for summer bedding. Sow the seeds in pans or boxes from January to March, and prick off the seedlings as soon as large enough to handle. Grow on steadily and gradually harden off in readiness for planting out after the Wallflowers and other spring bedders have been removed. After flowering it will save trouble to consign the plants to the waste heap and again raise a sufficient supply to fill their places in the following spring. When grown as perennials, seed should be sown in July or August. Leave the plants in the seed-bed until ready for transfer to final positions. These will stand the winter and come into flower earlier than plants from spring-sown seed.
AQUILEGIA
Columbine. Hardy perennial
Since the introduction of the long-spurred hybrid varieties the Aquilegia has become exceedingly popular. Like the Nasturtium, it is particularly accommodating in character, and will thrive on poor soil and amid surroundings altogether uncongenial to many other subjects. Several of the fine varieties which have been recently introduced are, however, worthy of a place in the best of borders. Sow in February or early in March in a frame, and plant out when strong enough, or sow in June in an open border. If the season is favourable, those sown early may bloom the first year; the remainder will flower in the year following.
ASPARAGUS
Greenhouse foliage varieties. Half-hardy perennials
The finely laciniated foliage of A. plumosus is greatly prized for bouquets, and the plant invariably commands attention as a decorative subject on the table or in the conservatory. A. decumbens has long tremulous branches of elegant dark green foliage, and the plant is admirably adapted for hanging-baskets. A. Sprengeri is distinct from both, but is also very ornamental in baskets. Sow all three varieties in pans during February or March, in heat; prick off the seedlings immediately they are large enough to handle, and grow on in gentle heat until the beginning of June, when cool-house treatment will suit them.
ASTER
Callistephus sinensis. Half-hardy annual
In high summer so many flowers are available that no difficulty arises in making a varied display. The real trouble is in discarding, especially for a limited area. But when summer begins to merge into autumn the choice is not so extensive, and among the annuals which then adorn the garden Asters are indispensable. This superb flower has been developed into many forms, and each class affords a wide range of magnificent colours. Yet it must be admitted that in the majority of gardens Asters are seldom grown in sufficient numbers, and it is not unusual to find the flowers small in size and poor in colour. In many cases we believe the reason to be that the culture of Asters is often commenced too late. Preparations should therefore be made in good time, and apart from providing the requisite number of plants for filling beds and borders, and for supplying cut blooms, others should be raised for flowering in pots. For indoor decoration full use is rarely ever made of Asters, although the colours include many delightful shades which may be employed with most telling effect.
To secure a long-continued display of bloom there must be several sowings, and the earliest will need the aid of artificial heat. One secret of successful culture is to give no check to the plant from its first appearance until the time of flowering; and a suitable bed must be prepared, whether the seed be sown on the spot or plants are transferred from other quarters.
Asters do not readily accommodate themselves to violent alternations of heat and cold, particularly in the early stage of growth, and therefore the most sheltered position in the garden should be chosen for them; but avoid a hedge or shrubbery, where strong growing trees rob the soil of its virtue. Begin the preparation of beds during the previous autumn by deep digging, and incorporate a liberal dressing of well-rotted manure as the work proceeds. On light and shallow soils it will do more harm than good to bring the raw subsoil to the surface, but the subsoil may with advantage be stirred and loosened by the fork, and if a little loamy clay can be worked into it the land will be permanently benefited.
A very stiff soil will, however, present greater difficulties; but if by free working it can be made sufficiently friable, Asters will revel in it, and produce flowers of a size and colour that will reward the cultivator for all his trouble. Throw the ground up roughly in October. The more it is exposed to the action of wind, snow and frost, the more thoroughly will the winter disintegrate its particles and render it fertile. Early in spring give another digging, and then work in a good supply of decayed manure, together with grit, charcoal, wood ashes, or other material that will help to render the soil rich and free. Aim at inducing the roots to go down deep for supplies—there will then be a cool moist bottom even in dry weather, and these conditions will do much toward the production of fine stocky plants capable of carrying an imposing display of flowers.
For sowings from the end of March to the middle of April prepare a compost consisting principally of decayed leaf-mould, with sufficient loam to render it firm, and sharp sand to secure drainage. Either pots or seed-pans may be used. Place these in a cool greenhouse, or in a Cucumber or Melon pit, or even on a half-spent hot-bed. Sow thinly; a thick sowing is very likely to damp off. Just hide the seed with finely sifted soil, and place sheets of glass at the top to prevent rapid evaporation. Give no water unless the soil becomes decidedly dry, and then it is better to immerse the pot or pan for half an hour than to apply water on the surface. When the plants attain the third leaf they can be pricked off into shallow boxes or round the edges of 3-1/2 inch pots. From these they either may have another shift singly into small pots, or may be transferred direct to blooming quarters. A high temperature is not requisite at any stage of growth, indeed it is distinctly injurious. From 55° to 65° is the extreme range, and the happy medium should, if possible, be maintained. Give air on every suitable occasion, and as the time for transferring to the open ground approaches, endeavour to approximate nearly to the outside temperature. The plants will then scarcely feel the removal.
Another and simpler proceeding produces fairly good results, and we describe it for the benefit of those whose resources may be small, or who do not care to adopt the more troublesome method. In some spot shaded from the sun make a heap of stable manure, rather larger than the light to be placed upon it. Level the top, and cover with four or five inches of rich soil. Place a frame upon it with the light a trifle open. When the thermometer indicates 60°, draw drills at six inches apart; sow the seed, and cover with a little sifted soil. The light had better not be quite closed, in case of a rise of temperature. As the plants thrive, gradually give more air, until, in April, the showers may be allowed to fall directly upon them in the daytime. When the Asters are about three inches high they will be quite ready for the open ground, and a showery day is favourable to the transfer. After the bed has served its purpose, the manure will be in capital condition for enriching the garden.
In the event of there being no frame to spare, drive a stake into each corner of the bed. Connect the tops of the stakes, about one foot from the surface of the bed, with four rods securely tied, and upon these place other rods, over and around which any protecting material at command may be used. With this simple contrivance it is quite possible to grow Asters in a satisfactory manner.
The finest Asters are frequently grown in the open air, entirely without the aid of artificial heat, and indeed without any special horticultural appliances. Those who possess the best possible resources will find additional advantage in resorting also to this mode of culture. It gives another string to the bow, and prolongs the season of flowering. For open-air sowings in April make the soil level and fine, and about the middle of that month draw drills three inches deep. In these place an inch of finely prepared rich soil, and if it is largely mixed with vegetable ashes, so much the better. The distance between the drills should be regulated by the variety. For tall-growing Asters twelve to fifteen inches between the rows will not be too much. Ten inches will suffice for the dwarfs. Sow the seed thinly and evenly, and cover carefully with fine soil. Commence early to thin the plants, always leaving the strongest, and arrange that they finally stand at from eight to fifteen inches apart according to the sort.
Keep the ground clean, and before the flowering stage is reached gently stir the surface, but not deep enough to injure the roots. An occasional application of weak manure water will be advantageous, but it must not be allowed to touch the foliage.
For tall varieties it may be needful to provide support. If so, place a neat stick on that side of the plant towards which it leans, as this takes the strain off the tying material, and saves the plant from being cut or half-strangled. In a dry season, and especially on light soils, there must be a bountiful supply of soft water, alternated every few days with the manure water already alluded to. Evening is the best time to apply it.
For show purposes rather more room is required than we have stated. Only about five buds should be matured by each plant, and these, of course, the finest. To prepare flowers for exhibition is in itself an art, and each cultivator must be guided by his own resources and experience.
Asters in pots make excellent decorative subjects. It is only necessary to lift them carefully from the borders with balls of earth surrounding the roots, and pot them just before the buds expand, or they may be potted up while in full flower without flagging.
The plants are liable to the attacks of aphis, both green and black. While under glass the pests can be destroyed by fumigation; but in the open a solution of some good insecticide may be administered with the syringe at intervals of about three days, until a clearance is effected. Other foes are the various grubs which attack plants at the collar. On the first sign of failing vigour, gently remove with a pointed stick the soil around the plant, and in doing this avoid any needless disturbance of the roots. Do not be satisfied until the enemy is destroyed.
AUBRIETIA
Hardy perennial
In the early months of the year few subjects in the garden present so gay an appearance as Aubrietias, for with the first approach of genial weather the cushion-like plants burst into a mass of delightful blossom. For spring bedding, edgings, and the rock garden Aubrietias are indispensable, and they make a particularly effective show when grown in conjunction with Yellow Alyssum and White Arabis. Aubrietias are easily grown from seed sown in May and June. The plants are best raised in pans of light rich soil and may be put out in autumn where required to flower in the following spring.
AURICULA
Primula Auricula. Hardy perennial
Keen is the enthusiasm of the Auricula amateur. The only complaint we ever heard about the flower is that its most devoted admirer cannot endow it with perpetual youth and beauty.
It is well to bear in mind that seed from a worthless strain requires just as much attention as that which is saved with all a florist’s skill from prize flowers. Some growers advocate sowing immediately the seed is ripe, but this intensifies the irregular germination that characterises seed of all the Primula species. Either February, March, or April may be chosen, and we give preference to the end of February. Use six-inch pots, and as there must be no doubt about drainage, nearly half-fill the pots with crocks, cover with a good layer of rough fibrous loam mingled with broken charcoal, and on the top a mixture of loam, decayed leaves, and sharp sand. Press the soil firmly down; sow thinly and regularly, putting the seeds in about half an inch apart; just cover them with fine soil, and place the pots in a cool frame or greenhouse, with sheets of glass over to prevent evaporation. Watering in the ordinary way is apt to wash out the seeds, and it is therefore advisable to immerse the pots in a vessel containing water until the soil has become saturated. Wait patiently for the plants. When they show four or six leaves, prick out into pans or boxes about two inches apart, and before the seedlings touch each other transfer to small pots. The surface soil in the pots may be lightly stirred occasionally to keep it free from moss. The plants must never be allowed to go dry, but as winter approaches water should be given more sparingly, and during sharp frosts it may be wise to withhold it entirely. There really is no need of artificial heat, for the Auricula is a mountaineer, and can endure both frost and snow. But we prize its beauty so highly that frames and greenhouses are properly employed for protecting it from wind, heavy rain, soot, dust, and all the unkind assaults of a lowland atmosphere, to which it is unaccustomed in a natural state. Still, the plants should be kept as nearly hardy as possible.
The Auricula is a slow-growing plant, and although there will probably be some flowers from seedlings in the second year, their value must not be judged until the following season. To the trained eye of the florist the Show Auriculas take precedence over the Alpine section; but for general usefulness the Alpines hold the first place. They may be fearlessly put into the open border, and especially the north border, where, with scarcely any care at all, they will endure the winter, and freely show their lovely flowers in spring.
BALSAM
Impatiens Balsamina. Half-hardy annual
The older methods of growing Balsams prescribed a false system, comprising disbudding, stopping, and other interferences with the natural growth of the plant. The rule of pinching back the leader to promote the growth of side shoots, and removing the flower buds to increase the size of the plants, was altogether vicious, because the natural growth is more elegant and effective. The finest flowers are produced on the main stem, and these are completely sacrificed by disbudding.
It is desirable to make two or three sowings of Balsam, say from the middle of March to the middle of May, the earlier sowings to be put on a sweet hot-bed, although March sowings will soon germinate in a frame, and the May sowing may be made in the open ground on a prepared bed. The soil at every stage should be rich and light, but not rank in any degree. Prick out the plants from the seed-pans directly the first rough leaves show, and soon after shift them again to encourage a stout dwarf habit. A sunny position should be chosen for the bed, in which they may be planted out about the first week of June, or earlier if the weather is particularly favourable. Heat, moisture, and a strong light favour a fine bloom, and, therefore, water must be given whenever dry weather prevails for any length of time. If kept sturdy while under glass, they will need no support of any kind, and although they are peculiarly fleshy in texture, it is seldom they are injured, even by a gale. When grown in pots throughout, the chief points are to shift them often in the early stages, to promote free growth in every reasonable way, and to cease shifting when they are in pots sufficiently large to sustain the strength of the plants. Generally speaking, eight-inch pots will suffice for very fine Balsams, but ten-inch pots may be used for plants from an early sowing. They will probably not show a flower-bud while increased pot room is allowed them; but as soon as their roots touch the sides of the pots the bloom will appear. It is occasionally the practice to lift plants from beds when pot Balsams are wanted. This method has the advantage of being the least troublesome, and as the plants need not be lifted until the flowers show, favourite colours can be chosen.
