Pumpkin

Description

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. 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 and for medical conditions. C. pepo seems more closely related to C. fraterna, though disagreements exist about the exact nature of that connection, too. It is a host species for the melonworm moth, the squash vine borer, and the pickleworm. They are also the preferred pollen for squash bees.Due to their varied genetic background, members of C. pepo vary widely in appearance, primarily in regards to their fruits. The plants are typically 1.0–2.5 feet high, 2–3 feet wide, and have yellow flowers. Within C. pepo, the pumpkins, scallops, and possibly crooknecks are ancient and were domesticated separately. The domesticated species have larger fruits and larger yet fewer seeds. Parthenocarpy is known to occur in certain cultivars of C. pepo.
