About this species

Cucurbita pepo has been cultivated for its edible fruits for thousands of years and remains a crop plant of great economic importance today. An extensive range of cultivars is available, including those grown to produce fruits for Halloween lanterns and pumpkin pies, courgettes (zucchinis), marrows, many types of squashes and ornamental gourds. It is important to note that the common names pumpkin and squash are used for more than one species of plant. For example the fruits of some cultivated forms of Cucurbita maxima, C. moschata and C. argyrosperma are also sometimes known as pumpkins and squashes.

Three subspecies are recognised:

  • Cucurbita pepo subsp. pepo (known only in cultivation)
  • Cucurbita pepo subsp. texana (known in cultivation and in the wild in southeastern USA)
  • Cucurbita pepo subsp. fraterna (known only in the wild in northeastern Mexico)
