The First Flowering of an Amorphophallus titanum  (Becc.) Becc. ex Arcang. Grown From Seed Collected by Jim Symon

The first four photos, taken May 1, 1998, are of an inflorescence of Amorphophallus titanum, grown from wild-collected seed discovered by Jim Symon. The seed was planted in February, 1995, and grown in the University of Missouri-St.Louis greenhouse by Kathy Upton. The next four photos show the inflorescence progressively opening.
