C. Maxima. Developed in the 1920’s at the University of North Dakota as a replacement for sweet potatoes, Buttercup is a triumph of traditional breeding. This squash is both insect & disease resistant, cold tolerant, & highly nutritious. Maturing in just 95 days, it is an excellent candidate for areas with very short growing seasons. Flavor & keeping qualities are not sacrificed for these advantages. Short vining habit makes for a tidy plot, reaching just six feet. Plants produce four to five fruits each, averaging three to six pounds. Harvest when the spot touching the ground turns orange. 30 seeds per packet. Burgess Buttercup Squash Seeds
