Amorphophallus paeoniifolius is a aroid from tropical Asia. The foliage is a large umbrella like foliage on top of a rough green and white speckled petiole. Mature plants can reach around 8 feet tall and the petiole can grow as 1 foot diameter. The flowers are one of the most odd of any I have grown. Often noted as other worldly. The flowers are 1 to 2 feet tall with a large dark maroon brain like spadix surrounded by a large spath that wraps around it. Plants are hardy zone 8-9.
Tubers are sold either bare-rooted or planted in large pots. The tubers softball size to grapefruit size. Limited quantity usually available.
