Tuffy Acorn Squash is widely acclaimed as the best-tasting of all the acorn varieties for its notably sweet, delicate flavor and more dry interior flesh. Well formed, vining plants set dark black-green fruits with heavy ribbing that average 2 pounds. A favorite for winter baking, Tuffy Acorn has a reputation for keeping an excellent shelf life when properly stored in dry, cool conditions, due to its tough, thick rind. Expect 5 to 8 fruits per plant. 90 days. Packet: 20 seeds.
