The Story
Plant Bio
A tuberous perennial from Southeast Asia, Amorphophallus atroviridis produces a single, large, highly dissected leaf on a mottled petiole, resembling a small tree. Before the leaf emerges, a striking inflorescence appears, consisting of a dark, velvety, black-purple spathe surrounding a spadix that emits a foul odor to attract pollinators.
This cultivar, Grey Expectations, features a unique greyish hue on the spathe and leaf stalks, adding an unusual and elegant coloration that contrasts with the typical vibrant greens and purples of the species.
