Oblong yellow-skinned winter squash 8-12 inches (20-30 cm) long and 4-5 inches (10-13 cm) diameter, weighing 4-8 pounds (1.8-3.6 kg).

Dark green large palmate foliage with light green veining. In the gourd family (Cucurbitaceae). Classified as C. pepo (not C. maxima or C. moschata). Winter squash — harvest mature when rind turns deep yellow and cannot be dented with a fingernail. Requires 100-110 days from seed — a limitation for short-season climates. Vines require 8-12 feet (240-360 cm) of space. Squash vine borer (Melittia cucurbitae) and powdery mildew are primary pests/diseases. Stores 2-3 months at 50-60°F (10-16°C). Open-pollinated — cross-pollinates with other C. pepo. Non-toxic (edible crop). Tender annual. Full sun. Growth rate is fast.
