Blue Hubbard is a New England heirloom winter squash grown in the region since the 1700s. Long vines yield powdery blue oval squash with hard shells and firm dry yellow flesh, some over 20 pounds.
Sow 1/2-1 inch deep indoors 3-4 weeks before the last frost or outside after frost in warm soil. Sprouts show in 7-10 days at 70-85ºF. Give plants 36-48 inches between hills on open ground.
