This is WIU Titan #2. As you may recall, we have four Amorphophallus titanum (Titan Arums) in the WIU Botany Greenhouse. Last year, May and June 2010, two of them produced inflorescences. Now, Titan #2 is producing an inflorescence. Yesterday morning it was measured to be 19.5" tall. Going by past experiences and data of previous Titans, I would think Titan #2 will open in two or three weeks.
