Cucurbita moschata

About

Cucurbita moschata is a species originating in the tropical Americas which is cultivated for edible flesh, flowers, greens, and seeds. It includes cultivars known in English as squash or pumpkin. Cultivars of C. moschata are generally more tolerant of hot, humid weather than squash of other domesticated species. C. moschata also exhibit a greater resistance to certain disease and insects, notably including to the squash vine borer. Commercially-made pumpkin pie mix is most often made from varieties of C. moschata.
