What are heirloom pumpkin seeds?

Heirloom pumpkin seeds are open-pollinated varieties that have been passed down through generations. Unlike hybrids, you can save seeds from heirloom pumpkins and grow the same variety year after year. All our seeds are non-GMO and open-pollinated.

What growing zone are your seeds tested in?

All our seeds are grown and tested on our Zone 6b homestead in Newton, Kansas. Most of our varieties also perform well in Zones 5-9. Each product listing includes specific growing zone recommendations.

Do you offer free shipping?

Yes! We offer free shipping on all orders over 0. Seeds ship via USPS First Class, and coffee ships fresh within 48 hours of roasting.

What makes your coffee different?

Our Prairie coffee is small-batch roasted right here on the Kansas prairie. We roast weekly to ensure freshness. Available in Prairie Sunrise (light roast) and Prairie Blaze (medium roast), both in ground or whole bean.

Are your pumpkin seeds vine borer resistant?

Many of our Cucurbita moschata varieties are naturally resistant to squash vine borers, including Seminole Pumpkin, Long Island Cheese, Tromboncino, and Mrs. Amersons. We highlight vine borer resistance on each product page.

Kansas Garden Seeds — Heirloom Pumpkins & Squash for Zone 6b

Every seed we sell ships from Newton, Kansas — Zone 6b, right in the heart of the Great Plains. We grow and trial our varieties in the same hot summers, late frosts, and clay soil you're dealing with. If a variety can't handle Kansas, it doesn't make the catalog.

Why Kansas Gardeners Choose Autumn Prairie

The squash vine borer is the number-one pumpkin killer in the Midwest. Every seed variety we carry is either naturally resistant (Cucurbita moschata) or a tested hybrid bred to survive vine borer pressure. No guesswork. No heartbreak in August.

Our collection includes heirloom varieties from around the world — Seminole pumpkins from Florida, Black Futsu from Japan, Ayote squash from Guatemala, Musquée de Provence from France — all proven in Kansas soil. Non-GMO, and selected for real-world performance in Zone 6b. Most varieties are open-pollinated heirlooms — we also carry a few F1 hybrids bred for extra disease resistance.

What Grows Best in Kansas

For first-time Kansas pumpkin growers, start with Seminole Pumpkin (bulletproof vine borer resistance), Waltham Butternut (the classic storage squash), or Dickinson (the original Libby's pie pumpkin). All three are heavy producers in our climate and tolerate the July heat that wilts most garden crops.

If you're looking for something unusual, try Shishigatani (a rare Kyoto heirloom) or Cushaw Green-Striped (an Appalachian classic that's been grown since the 1800s). Both thrive in Kansas.

Planting Guide for Kansas (Zone 6b)

Direct sow after last frost — typically mid-May in central Kansas. Soil temperature should be at least 65°F. All our Cucurbita moschata varieties need 95–120 days to mature, so timing matters. Start seeds indoors in late April if you want a head start.

Space hills 6–8 feet apart. Moschata varieties are vigorous runners — give them room. Mulch heavily to retain moisture during July and August heat.
