Cucurbita andreana is a plant species of the genus Cucurbita. It is native to Argentina. C. andreana fruits are smaller and less palatable than those of C. maxima.
The species Cucurbita maxima originated in South America from wild C. andreana over 4,000 years ago. The two species hybridize quite readily but have noticeably different calcium levels.C. andreana has orange flowers and bright green striped fruit. It prefers full sun and well drained soil. Extrafloral nectaries are present in C. maxima but not necessarily C. andreana.
