About
Cucurbita pepo is a cultivated plant of the genus Cucurbita. It yields varieties of winter squash and pumpkin, but the most widespread varieties belong to the subspecies Cucurbita pepo subsp. pepo, called summer squash.
It has been domesticated in the Americas for thousands of years, from where it was spread by early colonisers to Europe and later across the rest of the Old World in the context of the Columbian Exchange. Some authors maintain that C. pepo is derived from C. texana, while others suggest that C. texana is merely feral C. pepo. They have a wide variety of uses, especially as a food source. C. pepo seems more closely related to C. fraterna, though disagreements exist about the exact nature of that connection, too.
Where it grows
The species is found from sea level to slightly above 2,000 m (6,600 ft).
Uses
Fresh squash is cut into spiral strips, folded into hanks and hung up to dry for winter use. The blossoms are fried in grease and used as a delicacy in combination with other foods. Fresh squash, either whole or in pieces, is roasted in ashes and used for food. In the Zuni culture, the gourds are made into cups, ladles, dippers, and storage receptacles. A poultice of seeds and blossoms was used to treat cactus scratches.
