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.

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.

History & Origin

Tromboncino (also called "zucchetta") is an Italian heirloom that has been grown in Italian kitchen gardens for generations. This unique climbing squash belongs to the moschata species, giving it natural resistance to squash vine borers, a massive advantage over standard zucchini. Young fruits are used like zucchini; mature fruits develop hard shells and sweet, dense flesh like winter squash. This dual-purpose nature makes it one of the most versatile squash in any garden.

In the Kitchen

Harvest young (12-18 inches) and use like zucchini, saute, grill, or spiralize into noodles. Let them mature on the vine for winter squash with sweet, nutty flesh perfect for soups and roasting. The long, curved shape slices into beautiful rounds for grilling or making zucchini fritters.
