[3] 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.

By the early 19th century, at least three varieties are known to have been commercially introduced in North America from seeds obtained from Native Americans.

[5] As of October 2024[update], Cucurbita andreana is accepted as a separate species by some sources,[7] and a subspecies of C. maxima by others.

[10] Buttercup squash, a common cultivar, can be roasted, baked, and mashed into soups, among a variety of filler uses, much like pumpkin.

[24] Since this plant requires a fair amount of hot weather for best growth, it has not become very well established in northern Europe, the British Isles, or in similar areas with short or cool summers.

Fertilization should be carried out based on soil test results and specific crop nutrient requirements.
