As of October 2024[update], Cucurbita andreana is accepted as a separate species by some sources,5 and a subspecies of C. maxima by others.6 It was first formally described by Charles Victor Naudin in 1896, in Revue Horticole.7 It is native to Argentina and Uruguay and is the ancestor of the domesticated forms. C. andreana fruits are smaller and not palatable.89 It hybridizes readily with individuals of other C. maxima subspecies.
C. maxima subsp. andreana has notably different calcium levels than individuals of other C. maxima subspecies.10 C. andreana has yellow flowers and bright green striped fruit. Extrafloral nectaries are present in C. maxima but not necessarily in C. andreana.11
Buttercup squash, a common cultivar, can be roasted, baked, and mashed into soups, among a variety of filler uses, much like pumpkin. It is extremely popular, especially as a soup, in Brazil, Colombia, and Africa.
All giant pumpkins (over 300 pounds or 140 kilograms) are of this species, including the largest pumpkins ever documented, which have attained a size of 2,749.0 pounds (1,246.9 kg) as of 2023[update].24
The seed of C. maxima is used in treating parasites in animals.25
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.26
The ideal soil pH range for cultivation ranges from 6.0 to 6.8.
Recommended spacing can vary depending on the specific variety, but generally, plants are spaced around 3–5 feet apart in rows that are approximately 6–10 feet apart. Planting depth of around 1–2 inches.
Fertilization should be carried out based on soil test results and specific crop nutrient requirements.27
Many cultivars of Cucurbita maxima have been developed. Only long-vining plants are known in this species.28 As in C. pepo, plants exist with a "bush habit" that is particularly evident in young plants, but older plants grow in the wild-type vining manner.29
