The plant grows to between 20–50 cm (8–20 inches) high and has small feathery leaves on either side of the stem. Chickpeas are a type of pulseb, with one seedpod containing two or three peas. It has white flowers with blue, violet or pink veins. Chickpeas need a subtropical or tropical climate with more than 400 millimeters (16 in) of annual rain. They can be grown in a temperate climate but yields will be much lower. There are two main kinds of chickpea (1) Desi, which has small, darker seeds and a rough coat, cultivated mostly in the Indian subcontinent, Ethiopia, Mexico, and Iran. (2) Kabuli, which has lighter colored, larger seeds and a smoother coat, mainly grown in Southern Europe, Northern Africa, Afghanistan, Pakistan and Chile, also introduced during the 18th century to the Indian subcontinent.
