Cassava, Manihot esculenta, is a perennial shrub in the family
Euphorbiaceae grown primarily for its storage roots which are eaten
as a vegetable. The cassava plant is a woody plant with erect stems
and spirally arranged simple lobed leaves with petioles (leaf
stems) up to 30 cm in length. The plant produces petal-less flowers
on a raceme. The edible roots of the plant are usually cylindrical
and tapered and are white, brown or reddish in color.
