Seminole River Pumpkin Seeds
Seminole Pumpkin - Heirloom
Cucurbita moschata | 95–100 Days | Open-Pollinated
This pre-Columbian crop was cultivated by the Calusa, Creek, and Miccosukee peoples of Florida long before European contact — Spanish explorers documented it growing in and around Native camps as far back as the 1520s.
The Seminole people named an entire stretch of Gulf coastline "Chassahowitza," meaning "pumpkin hanging place," a nod to their traditional method of planting these vines at the base of trees and letting the fruit hang from the canopy above — a remarkably clever way to keep the harvest out of reach of pests and floodwaters.
What survived those centuries is nothing short of extraordinary. The Seminole Pumpkin produces medium-sized fruits — typically 6 to 12 pounds — that vary in shape from round to pear to oblong, with a tough, sandy-tan rind that matures from green. That rind isn't just for show: it's one of the toughest of any pumpkin variety, giving these fruits a storage life that can stretch up to a full year in the right conditions. Inside, the dense orange flesh is sweet and smooth, tasting somewhere between a fine butternut squash and a classic pie pumpkin. It's exceptional in soups, pies, roasted dishes, and baked goods of all kinds — and even the flowers are edible, delicious raw, stuffed, or fried.
Beyond the flavor and the history, this variety is a workhorse in the garden. It shrugs off heat, humidity, vine borers, and downy mildew — conditions that would flatten most other squash. Gardeners in the Deep South especially will find it grows with a vigor that borders on wild. The vines can push well past 20 feet and thrive on surprisingly little intervention. More than a few growers describe it as one of the easiest crops they've ever put in the ground.
A living piece of American history that also happens to taste incredible. You really can't ask for more.
When to Plant Seminole Pumpkins are a warm-season crop through and through. Direct sow after your last frost date once soil has warmed to at least 65–70°F. In Florida and the Deep South, seeds can go in the ground anywhere from late winter through midsummer, with a fall planting window as well — just make sure you have 100 days before your first expected frost. In cooler northern climates, starting seeds indoors 2–3 weeks before your last frost gives the long season a helpful head start.
Starting Indoors Sow seeds about an inch deep in individual biodegradable pots to minimize root disturbance at transplant time. Keep soil warm — 75–85°F is ideal — and expect germination in 7–14 days. Harden off transplants over 5–7 days before moving them to the garden. Transplant out once nights are reliably warm.
Direct Sowing Plant 3 seeds per hill, about an inch deep, and thin to the strongest plant once true leaves appear. Give each hill a wide berth — these vines need room to do what they do. Rows should be at least 6–8 feet apart, and individual plants 2–3 feet apart at minimum.
Location & Soil Full sun is a must. Seminole Pumpkins historically climbed trees and fences to chase it, and your garden planting should reflect that spirit — give them something to climb or a wide open area to sprawl. Soil should be well-draining and amended with compost before planting. A raised hill or mound 8–12 inches tall improves drainage and warms up faster, giving the vines an early boost.
Watering Water at the base of the plant, not overhead — wet foliage is the main invitation for mildew issues. These plants are notably drought-tolerant once established, but consistent moisture during flowering and fruit development leads to better yields. Don't overdo it; they genuinely do well with less attention than most squash.
Pest & Disease Resistance This is one of the Seminole Pumpkin's biggest selling points. Where other squash varieties succumb to vine borers, Seminole Pumpkins keep right on growing — their tougher stems are far more resistant to borer damage. They also show strong natural resistance to downy mildew. Practice crop rotation year to year as a basic precaution, but don't be surprised if this is simply your most trouble-free squash.
Harvesting Fruits are ready when the stem turns brown and woody and the rind has hardened fully and reached its mature tan-orange color. Cut the stem a few inches above the fruit using sharp pruners rather than twisting it off — a clean stem helps the pumpkin store longer. Once harvested, cure in a warm, well-ventilated spot for a week or two before moving to long-term storage. In ideal conditions — cool, dry, good airflow — these pumpkins can hold for up to a year.
Young green fruits can also be harvested early and cooked like summer squash, and the yellow blossoms are a bonus harvest throughout the season.
Saving Seeds Seminole Pumpkin is open-pollinated and an excellent seed-saving variety. Since it belongs to the species Cucurbita moschata, it can cross with butternut squash and calabaza — isolate by at least a half mile if saving seeds for true-to-type offspring. Seeds are fully mature when the fruit stem has turned brown and woody. Scoop seeds from a fully ripe fruit, rinse well, and dry on a screen away from direct sunlight for 1–2 weeks. Store in a cool, dry place for up to 5 years.
