Delicata Squash Seeds (Sweet Potato Type) Heirloom Vegetable. Short vines produce fruit about 15-20 cm (6-8″) long and 9 cm (3.5″) in diameter that are cream coloured with attractive thin green stripes. Unlike most of the winter squash, Delicata has a thin edible skin so no peeling is required before eating! This unique looking squash has very sweet orange flesh and is excellent for stuffing and baking. A good winter keeper.
