Origins and History
Thelma Sanders Sweet Potato Squash is a cherished heirloom variety with roots in the Midwest of the United States. It was introduced by Seed Savers Exchange after being shared by Thelma Sanders of Missouri, who lovingly cultivated and preserved this squash. Its name honors both its caretaker and the sweet, nutty flavor reminiscent of baked sweet potatoes. As a long-standing heirloom, it represents a lineage of seed stewardship and culinary heritage, keeping alive traditions of home gardening and seed saving.
Appearance and Characteristics
This acorn-type squash is notable for its beautiful creamy, buff-colored skin and distinctive ribbed, acorn-like shape. The fruits typically weigh between 1–2 pounds, making them easy to handle in the kitchen. Its dense flesh is a warm golden-orange, offering a smooth texture and natural sweetness. The vines are vigorous and productive, often yielding a generous harvest of uniform fruits that also store well through the winter months.
Culinary Uses
Praised for its rich, sweet flavor, Thelma Sanders Sweet Potato Squash is particularly valued as a substitute for sweet potatoes. When roasted, baked, or mashed, the flesh develops a caramelized sweetness with nutty undertones. It is excellent for savory side dishes, hearty soups, casseroles, or even pie fillings. Its size and shape also lend themselves well to being halved, stuffed, and baked, making it a versatile and delightful ingredient in home kitchens.
Growing Tips
Adaptable and resilient, this squash thrives in USDA Hardiness Zones 3–9. Seeds should be sown after the danger of frost has passed, once soil temperatures reach at least 65°F (18°C). Plant seeds 1 inch deep, spacing them 18–24 inches apart in rows or hills with 3–4 feet between mounds to allow for vine growth. Full sun and fertile, well-drained soil enriched with organic matter encourage healthy growth. Regular watering is essential, particularly during fruit set, but avoid wetting foliage to reduce the risk of mildew.
Harvesting Guidance
Fruits are typically ready to harvest about 85–100 days after planting, when their rinds harden and resist pressure from a fingernail. Squash should be cut from the vine with a few inches of stem intact to prolong storage life. Once harvested, they can be cured in a warm, dry place for 1–2 weeks, which deepens flavor and improves keeping quality. Properly stored in a cool, dry location, Thelma Sanders Sweet Potato Squash can last for several months, providing a dependable winter staple.
