About

Cucurbita argyrosperma, commonly known as cushaw, kershaw, or silver-seed gourd, is a species of squash grown most frequently in North and Central America, and believed to originate from southern Mexico. This annual herbaceous plant is cultivated for its nutritional value: its flowers, shoots, and fruits are all harvested, but it is cultivated commonly in its native range for seeds.
