Table Queen Squash Seeds (Winter Type) Heirloom Vegetable. Introduced in 1913, Table Queen Squash is an early cropping variety producing acorn shaped fruits roughly 15 cm (6″) in diameter. The hard, dark green shell hides pale yellow, exceedingly sweet flesh whose taste rivals that of the sweet potato! Sow seed directly into the garden when soil temperatures exceed 30 C (86 F). Very warm soil temperatures increase germination speed and prevent seed rot. Some gardeners report success with seed sown indoors with bottom heat. Only transplant to the garden when soil temperatures are above 15 C (60 F).
