Konjac is a perennial plant. It grows from a large corm up to 25 cm in diameter. It has a single leaf of about 1.3 metres in length, across, bipinnate, and divided into numerous leaflets. The flowers are produced on a spathe (a leaflike bract that encloses or subtends a flower cluster) enclosed by a dark purple spadix (a fleshy club-like spike bearing minute flowers). Flowering occurs in early spring if the corm is mature. The plant has long been used in China, Japan and South-East Asia as a food source and as a traditional medicine.
