Species Notes
Description
Cucurbita maxima, one of at least five species of cultivated squash, is one of the most diverse domesticated species. This species originated in South America from the wild subspecies Cucurbita maxima subsp. andreana over 4,000 years ago. Cucurbita maxima, known for modern varieties as Hubbard, Delicious, Marblehead, Boston Marrow, and Turks Turban, originated in northern Argentina near the Andes or in certain Andean valleys. Secondary centers of diversity include India, Bangladesh, Myanmar, and the southern Appalachians.
