The Corpse Flower, Amorphophallus titanum, is developing a flowering bud in the UMSL greenhouse. This particular plant, grown from seed in 1995 at UMSL, collected by James Symon, also bloomed in 1998. Two of its siblings have also bloomed at UMSL, in 2001 and 2009. When this plant bloomed in 1998, it surprised everyone by being capable of flowering at a very small size and weight, just under 3 pounds. It was the first of all the seeds that James Symon distributed around the world to bloom, and the first one to bloom in the United States since 1939. This is the "archetype", the original, the first, and is nicknamed Archie. Learn more about the Titan Arum
