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.

History & Origin

Developed in the 1960s at the University of Massachusetts Waltham Field Station by breeder Bob Young. Waltham Butternut won the prestigious All-America Selections award in 1970 and quickly became the most widely grown butternut variety in North America. Its uniform bell shape, smooth tan skin, and small seed cavity set the standard that all other butternuts are measured against. A true heirloom that has stood the test of time.

In the Kitchen

The quintessential soup squash, peel, cube, and simmer with aromatics for a velvety butternut soup. Equally excellent roasted with olive oil and sage, pureed into risotto, or used as ravioli filling. Stores 3,6 months in a cool, dry place, developing sweeter flavor over time. The dense, fine-grained flesh holds its shape beautifully when roasted or cubed into stews.
