A rare plant is about to bloom at Cal Poly. For the first time in Cal Poly’s history a Titan Arum or corpse flower, Amorphophallus titanum, will bloom. This plant makes the world’s largest unbranched inflorescence (cluster of flowers). The bloom can grow to more than eight feet in height and three feet in diameter. It is native to tropical forests and is rarely seen. Cal Poly’s horticulture and botany students have been growing these plants for over 10 years but have never had one flower.
