The rare Amorphophallus titanum plant bloomed on June 19, 2022. Titan Arum The Titan Arum, Amorphophallus titanum, has been called the world's largest flower, with a bloom that can grow to more than 8 feet in height and 4 feet in diameter. At the peak of its growth, the Titan Arum can grow up to 6 inches a day! It is a rare tropical plant native to the equatorial rainforests of Sumatra, Indonesia. When in flower, it exudes a foul stench that smells like rotting meat. For that reason, Indonesians call it Bunga Bangkai, which means "Corpse Flower." The plant grows from a large corm, a bulb-like tuber, under the soil. The visible parts are the spadix (the fleshy upright column) and the spathe (the petal-like outer covering). When the plant blooms, the spathe opens to reveal a velvety maroon interior and begins to emit a foul stench, earning it the nickname "Stinky Plant." Though everyone smells something different, the scent is made up of several different compounds: primarily dimethyl trisulfide (stinky cheese or boiled cabbage) and dimethyl disulfide (garlic), but also levels of trimethylamine (rotting fish), isovaleric acid (sweaty socks), benzyl alcohol (sweet flowery scent), and indole.[?][?] The purpose of the putrid stench? To attract nighttime pollinators like flesh flies, carrion beetles, and sweat bees. [?] Corpse Flowers at The Huntington In August 1999, a Corpse Flower bloomed for the first time at The Huntington. This rare occurrence provided an opportunity for hundreds of visitors to witness one of the wonders of the botanical world. Since that extraordinary event, The Huntington has shared the flowering of this rare species with the public in seven subsequent years. Currently, we maintain several dozen plants of Amorphophallus titanum in our greenhouses and planted in the Conservatory. Visitors gather to smell the Corpse Flower's foul stench during the August 2018 bloom. Visitors gather to smell the Corpse Flower's foul stench during the August 2014 bloom.

Visitors view the Corpse Flower in bloom Visitors capture a previous bloom at The Huntington. Nobody can predict when a Corpse Flower will bloom. A Titan Arum in bloom is as rare as it is spectacular. A plant can go for many years without flowering. When the corm comes out of dormancy and a bud emerges, it will either develop into a flower or a new leaf; it's when we see the tip of the emerging spadix that we know a bloom will occur. Being in the right place at the right time to see one of these magnificent plants in bloom can be a once-in-a-lifetime treat! Corpse Flower Lifecycle corpse flower lifecycle History of the Corpse Flower The Corpse Flower, or Titan Arum, is native to the rainforests of western Sumatra, Indonesia, where it grows on limestone hills at low elevations, in forest openings where there is enough light and space to produce its massive leaf and inflorescence, or flower-bearing structure. The climate is warm and rainy, with little variance throughout the year. Although it is one of the most famous plants in the world, little is known of its natural history. Corpse Flower Anatomy The size of the Corpse Flower bloom is probably its greatest attraction. In 2009, the tallest flowering specimen at The Huntington was almost 7 feet tall. The record holder comes in at over 12 feet tall. The "tuber," which is actually a corm, can weigh over 300 pounds, and the solitary umbrella-like leaf can be over 15 feet tall. But it's the rotting flesh smell of the flowers that makes this plant so memorable and notorious. Adding to the mystique is the ephemeral nature of such a massive flowering effort, lasting only two to three days, and the rarity of seeing a specimen in bloom at any time, anywhere. When the Titan Arum blooms, it comes straight out of the soil from an underground corm, looking like a giant bud without any foliage. But the plant does produce a single giant leaf when it isn't in bloom. However, you might not recognize it as a leaf. A mature plant will produce a leaf about 12 feet tall, consisting of a smooth stem topped with a fringe of leaflets. The entire "leaf" resembles a slender, green palm tree. Several of them are on display in The Huntington's Rose Hills Foundation Conservatory for Botanical Science. The leaf can last longer than a year before it dies away. What is often referred to as this plant's flower is an inflorescence, a specialized structure that supports small individual flowers. The Corpse Flower produces the most massive, unbranched inflorescence of any flowering plant. Common to all members of the aroid family Araceae, the inflorescence consists of an outer protective sheath (the spathe) that surrounds a central column bearing small individual flowers (the spadix). Better-known members of this family include philodendrons, anthuriums, calla lilies, and pothos, among others. Ready, Set, Stink Just as notable as the size of this plant's bloom is the odor it emits when it is ready for pollination. On the first evening the spathe opens, a cocktail of powerful chemicals is released. The inflorescence also generates heat to assist in volatilizing these chemicals. This extraordinary action by the plant makes it easier for pollinators such as sweat bees and other insects to find the flowers. In the first phase, the female flowers are receptive to pollination, and in the second phase, on the second day, male flowers release their pollen. This carefully timed arrangement helps ensure that cross-pollination and fertilization will only occur between different individual plants. Do I Have One at Home? While Amorphophallus titanum is very rare, many similar (but much smaller) plants can be found growing in home gardens. The closest relative may be Amorphophallus rivieri, which grows to a height of about 4 feet and smells nearly as bad as its larger cousin. Two other related plants are the Dragon Arum (Dracunculus vulgaris), which grows to about 2 to 3 feet in height, and the Voodoo Lily (Sauromatum venosum), which grows to 12 to 18 inches in overall height. Calla lilies, anthuriums, and philodendrons are also members of the same family. Ask Our Stinky Expert We've gathered up your most frequently asked questions and answered them here. Do you have a question about the Corpse Flower? Ask our Stinky Expert! How long does it take for the bloom to actually open? Minutes? Hours? Individual bloom times vary, but typically it's several hours from when the bloom begins to open until it's fully open. --------------------------------------------------------------------- I smelled it when it bloomed last year--it really stinks! What makes it smell like rotten meat? The chemicals responsible for the odor were once thought to be putrescine and cadaverine, which are the chemicals that produce the odor in decaying animal flesh. Researchers recently analyzed the odors of several species of Amorphophallus and found the chemicals responsible for that of A. titanum (and other species) to be dimethyl disulfide and dimethyl trisulfide. As a comparison, one of the chemicals responsible for the odor of rotten eggs is hydrogen sulfide. --------------------------------------------------------------------- Once it flowers, how long before it closes and collapses? In other words, once we get word that it's in bloom, how quickly should we get over there? The bloom typically lasts only one or two days. --------------------------------------------------------------------- Is the plant also known as Rafflesia? No, Rafflesia, although also from Indonesia and other parts of southeast Asia, is in a different family and unrelated to Amorphophallus. Rafflesia has the distinction of having the largest individual flower, up to about 3 feet across. --------------------------------------------------------------------- How do you pollinate it once the bloom opens? A good quality paintbrush--preferably sable--is used to dab up the "donor pollen" from male flowers and is applied to the receptive stigmas of the female flowers on another plant. It takes two! The window of opportunity for this is only a couple of days because on the first day after opening, the female flowers are receptive but the male flowers have not yet shed their pollen. That happens the second or third day. This natural mechanism, the successive maturation of female and then male flowers on a plant, prevents autogamy, or self-pollination, to maximize the distribution of genes and maintain more adaptive genetic diversity. --------------------------------------------------------------------- I think I have one growing in my yard. Is that possible? It's possible! The Corpse Flower prefers an evenly warm and humid environment such as a greenhouse. We recently received a picture from someone who had one blooming in a container in his backyard in Seal Beach! While Amorphophallus titanum is very rare, many similar but much smaller plants can be found growing in home gardens. The closest relative may be Amorphophallus rivieri, which grows to a height of about 4 feet and smells nearly as bad as its larger cousin. Two other related plants are the Dragon Arum (Dracunculus vulgaris), which grows to about 2 to 3 feet in height, and the Voodoo Lily (Sauromatum venosum), which grows to 12 to 18 inches in overall height. Calla lilies, anthuriums, and philodendrons are also members of the same family. --------------------------------------------------------------------- Can I buy my own Stinky plant? Yes! There are many sources online to purchase an Amorphophallus titanum. This rare plant is for plant enthusiasts who want a challenge and will be committed to nearly a decade of nurturing and pampering this rare and attractive giant. --------------------------------------------------------------------- To what taxonomic class, order, and family does genus Amorphophallus titanum belong? Family: Araceae, Order: Arales, Class: Liliopsida (monocots) --------------------------------------------------------------------- The "Big Stinker" in 1999 In the summer of 1999, The Huntington was the focus of worldwide attention when it exhibited the first Amorphophallus titanum ever to bloom in California. It was only the 11th recorded bloom of one of these plants in the United States. During the Titan's short bloom, Huntington botanists hand-pollinated the plant with its own pollen, using an experimental technique (self-pollination is normally impossible). The procedure was a success, resulting in fruit and 10 fertile seeds from which several seedlings eventually were produced. Today, after a number of other successful blooms and pollinations, there are several generations of "Little Stinkers" in the botanical greenhouses, waiting for their moment to bloom. From Jungle to Greenhouse The Corpse Flower was first made known to the outside world by Italian botanist and explorer Odoardo Beccari in 1878. Seeds and corms brought to Italy at that time were shared with other gardens. The first flowering of the Corpse Flower in cultivation was in 1889 at the Royal Botanic Gardens in Kew, England, from the Beccari introduction. It flowered in the Western Hemisphere for the first time at the New York Botanical Garden in 1937. Few specimens of Amorphophallus titanum were grown or flowered until the 1990s, when seeds were gathered in the wild and distributed widely among botanical gardens and private collectors. Since then, this plant has bloomed on over 500 occasions in gardens around the world. Research, Education, and Conservation The blooming of a rare plant like Amorphophallus titanum provides The Huntington with an opportunity to pursue three of its most important missions: research, education, and conservation. With each flowering, botanists learn more about this unusual plant, while The Huntington shares with its visitors not only some fascinating new facts, but also an increased appreciation for the wonder and diversity of the plant kingdom. Through ongoing conservation efforts, The Huntington helps to protect rare and endangered plants from extinction. The Huntington's Rose Hills Foundation Conservatory for Botanical Science showcases many amazing plants from around the world, including Amorphophallus titanum, with interactive exhibits for families that encourage curiosity and discovery.
