Question: Where do cashews grow, on trees or bushes, and do they have shells?
Answer: The cashew is a tropical and subtropical evergreen shrub or tree. It grows where soil is fertile and humidity high. Cashews are native to tropical Central and South America, and are now abundant in East Africa and India. Cashews do have shells, actually like two walls. The thin outer shell is smooth and glasslike. The inner shell is hard and must be cracked like other nuts. The fruits are picked by hand, and the nuts are usually first detached, then sun dried.
