Blue Hubbard, Heirloom Winter Squash Seeds

Blue Hubbard — The Legendary Storage Squash With 15–40 lb Blue-Gray Fruits and Sweet Golden Flesh

Blue Hubbard is the winter squash that commands attention. Huge, teardrop-shaped fruits weighing 15–40 pounds with a distinctive blue-gray skin so hard it makes Blue Hubbard one of the longest-lasting squashes in winter storage — seeds remain viable for 6 years under cool, dry conditions, and the fruits themselves keep for months. Inside, sweet, fine-grained, golden flesh is exceptional for baking, pies, and soup. Give the vines plenty of room to run, or train them up a fence to save space. A true heirloom that rewards the gardener who has the patience to grow it. 100 days.

Growing Notes

Direct sow outdoors after last frost when soil has warmed to at least 65°F, or start indoors 3–4 weeks before last frost. Sow seeds 1 inch deep in fertile, well-draining soil. Space plants 48–60 inches apart in full sun — vines need ample room. Water consistently. Harvest at 100 days when rind is hard and fully blue-gray. Cure in a warm, dry location for 10–14 days before storage.
