Overview

Blue Hubbard is the big American storage squash, an heirloom with warty, thick blue-gray skin and fruit usually 12 to 15 pounds and often much larger. The flesh is deep orange, dry and dense with a richer, more complex flavor than butternut, and it is prized for pies and soups. Vigorous vines spread 8 to 15 feet and set one or two fruit each. Sow 1 to 1.5 inches deep in hills of three after soil reaches 70F, thin to two, and count on 100 to 110 days; in hot regions a late-summer sowing for a fall harvest works well. Harvest once the skin is hard and fully colored, cure 10 to 14 days in warmth, and it keeps six months or more at room temperature.
