- Description
-
Winter squash or pumpkin is a warm-season annual vegetable vine in the Cucurbitaceae (cucumber) family native to South America. Cucurbita is Latin for gourd and maxima is Latin for largest, because these plants can produce fruits that are very very large.
This large vine trails along the ground or climbs up structures using tendrils. It has yellow fruit-bearing flowers that are produced in the fall. The fruits have a mild flavor and can be fried, baked, added to pasta, used in soups, and more. Winter squash is an aggressive grower and prefers moderately moist soil with full access to sunlight.
This vine is best suited for large landscapes, but performs well in vegetable gardens, on trellises, and as a cover for exposed soil. It is easily sown from seed, especially when soils are warm. Transplant in late spring, early summer, or after the last frost.
