Pumpkin flower, Cucurbita moschata

''Cucurbita moschata'' is a species originating in either Central America or northern South America. It includes cultivars known as squash or pumpkin. ''C. moschata'' cultivars are generally more tolerant of hot, humid weather than cultivars of ''C. maxima'' or ''C. pepo''. They also generally display a greater resistance to disease and insects, especially to the squash vine borer.
