Arisaema flavum is a tuberous perennial from the arum family, native across north-eastern Africa and southern Asia, with yellow-green flowers in a hooded spathe. It is grown mainly in gardens and collections rather than widely as a houseplant, and it needs a dormant winter season.

About
Arisaema flavum is a species of flowering plant widespread across north-eastern Africa and southern Asia. It is native to Ethiopia, Somalia, the Arabian Peninsula, Pakistan, Afghanistan, Nepal, Assam, Himalayas, Tibet, Yunnan, and Sichuan. The species epithet flavum is Latin for yellow and indicates its flower colour.
Uses
It is a famine food, eaten during periods of crop failure or famine in the Konso special woreda, where it is endemic. It is preferred to other species of Arisaema due to its relatively acceptable taste, can be prepared within a short time, and is less perishable. But all varieties must be crushed and dried prior to further preparation. The dried parts are then ground to powder, which is mixed with water and cooked like maize for approximately 30 minutes.
