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 orders of $25 or more. Orders under $25 pay USPS calculated shipping. 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.

What are heirloom pumpkin seeds?

Heirloom pumpkin seeds come from open-pollinated varieties that have been grown and saved for generations. Unlike F1 hybrids, heirloom seeds breed true — meaning you can save seeds from your harvest and grow the same variety again next year. Heirloom pumpkins are prized for superior flavor, genetic diversity, and historical significance.

What is the best heirloom pumpkin for pies?

Long Island Cheese Pumpkin is widely considered the best heirloom pumpkin for pies, producing dense, sweet, low-moisture flesh with superior flavor to canned pumpkin. Dickinson pumpkin (the original Libby's variety) and Musquee de Provence are also excellent pie pumpkins. All three are Cucurbita moschata heirlooms with rich, smooth flesh.

Are heirloom pumpkin seeds open pollinated?

Yes. All true heirloom pumpkin varieties are open-pollinated, meaning they are pollinated naturally by wind or insects rather than controlled hand-pollination used for F1 hybrids. Open pollination means the seeds reproduce true to type, so you can save them for replanting. F1 hybrids are not heirlooms, even if they are open-pollinated.

What heirloom pumpkins grow best in Kansas?

The best heirloom pumpkins for Kansas Zone 6b are Cucurbita moschata varieties: Seminole pumpkin (heat and borer resistant, 100 days), Long Island Cheese (excellent pie pumpkin, 100 days), Waltham Butternut (85 days, award-winning), and Dickinson (100 days, classic pie pumpkin). These heirlooms were developed in conditions similar to Kansas summers and thrive with less fuss than pepo types.

Can I save seeds from heirloom pumpkins?

Yes — seed saving is one of the great advantages of heirloom varieties. Allow the fruit to fully ripen on the vine (past eating stage), scoop out the seeds, rinse off the flesh, and dry them flat for 2-4 weeks. Store in a cool, dry, dark location. Heirloom pumpkin seeds remain viable for 4-6 years when stored properly.

How many seeds come in a packet of heirloom pumpkin seeds?

Autumn Prairie Pumpkins seed packets contain 10 or 20 seeds per pack depending on the variety and pack size you choose. Given that pumpkin germination rates run 80-95% with proper soil temperature (65F+), 10 seeds typically yield 7-9 plants — more than enough for a home garden row or raised bed.

Heirloom Pumpkin Seeds: Varieties, Growing Tips & Kansas Guide

Heirloom pumpkin seeds connect you to a history of growing that predates the industrial seed industry. These are varieties that were grown, saved, and passed down because they worked. Because they tasted good. Because they survived bad summers, vine borers, and early frosts and still produced something worth putting on the table.

At Autumn Prairie Pumpkins, we grow and source heirloom varieties selected specifically for Kansas Zone 6b conditions, hot summers, strong winds, and squash vine borer pressure that would destroy most catalog varieties. Every seed we sell has been tested in real garden conditions, not just greenhouse trials.

What Makes a Pumpkin Seed an Heirloom?

True heirloom pumpkin seeds are open-pollinated varieties that have been grown and selected for at least 50 years (many for centuries). Unlike F1 hybrid seeds, heirlooms breed true, the seeds you save from your harvest will grow the same variety next season. This genetic stability is what makes heirlooms valuable for seed savers, small farmers, and gardeners who want a real relationship with their food plants.

Key traits that define heirloom pumpkins:

Open-pollinated, reproduces true from saved seed
Genetically stable, consistent results year after year
Selected over time, survivors of real growing conditions, not lab optimization
Flavor-forward, bred for taste and utility, not shelf life or uniformity

Our Core Heirloom Varieties

Seminole Pumpkin

The original Florida Native. The Seminole people grew this pumpkin for centuries in conditions far hotter and more humid than Kansas. Result: a moschata heirloom with almost legendary heat tolerance, strong vine borer resistance, and a nutty, dense flesh that works for cooking, curing, and long storage (up to a year in a cool cellar). If you grow one heirloom pumpkin in Kansas, this is the one.

Long Island Cheese Pumpkin

Named for its resemblance to a wheel of cheese, this 19th-century Long Island heirloom is widely considered the finest pie pumpkin in existence. The flesh is dense, sweet, low-moisture, and deep orange. Produces 6-10 lb fruits that store for months. Moschata species, so it handles Kansas summer heat without complaint.

Mrs. Amerson's Pumpkin

A rare moschata heirloom with limited commercial availability. Passed down through a single family line, this variety produces large, deeply ridged fruits with exceptional flavor and multi-month storage. The kind of seed you find at an estate sale or a seed swap, not a big catalog. We grow it here so it stays available.

Musquee de Provence

The French farmer's pumpkin. Flat, deeply ribbed, and a burnished tan-orange at maturity. Musquee de Provence has been grown in southern France for centuries for its rich, aromatic flesh and excellent storage. It performs well in Kansas heat and looks stunning on a harvest table or market stand.

Waltham Butternut

The award-winning butternut developed by Bob Young in Waltham, Massachusetts in the 1940s. It won the All-America Selections award in 1970 and has remained a gardener and farmer favorite since. Reliable, productive, 85-day maturity, excellent flavor. One of the few heirlooms that's also a commercial standard.

Why We Focus on Cucurbita Moschata Heirlooms

Most heirloom pumpkin catalogs lead with Cucurbita pepo, jack-o-lanterns, Sugar Pies, Delicata. These are beautiful varieties, but they're vulnerable to squash vine borers, heat stress, and powdery mildew. In Kansas, they're a gamble every season.

Cucurbita moschata heirlooms are a different animal entirely. Developed across tropical and subtropical growing regions, Florida, the American Southeast, the Caribbean, southern France, West Africa, Polynesia, these varieties evolved under conditions similar to a Kansas summer. They don't just tolerate the heat. They expect it.

And their thick, corky stems are highly resistant to squash vine borer larvae, the single biggest pest threat to Kansas pumpkin growers. The same adaptation that helped them survive insect pressure in their home climates protects them here.

Heirloom Seeds vs. Hybrid Seeds: Which Is Right for You?

We grow and sell both, because the honest answer is that it depends on what you're trying to do.

Choose heirloom pumpkin seeds if you:

Want to save seeds from your harvest
Value flavor and texture over uniformity
Are building a seed-saving practice
Prefer varieties with documented history and proven performance

Consider F1 hybrid seeds if you:

Want maximum disease resistance in a single season
Need predictable fruit size for market or display
Don't plan to save seeds

We're transparent about which varieties are which. Every listing on our store clearly identifies heirloom (open-pollinated) vs. F1 hybrid varieties.

How to Choose the Right Heirloom Pumpkin Seed for Your Garden

Start with your why. Are you growing for:

Cooking and pies? Start with Long Island Cheese or Musquee de Provence
Storage (6+ months)? Seminole pumpkin or Mrs. Amerson's
Farmers market presence? Musquee de Provence or Jarrahdale (visual standouts)
First-time grower? Waltham Butternut, forgiving, reliable, 85-day maturity
Vine borer pressure? Any moschata, they all carry resistance
Extreme Kansas heat? Seminole or Tahitian Melon

Germination and Growing Tips

Heirloom pumpkin seeds germinate best in warm soil (65-85F). Don't rush planting, a seed sown in 70F soil germinates in 5-7 days. The same seed in 55F soil may take 2-3 weeks or fail entirely.

In Kansas Zone 6b: Start seeds indoors 3-4 weeks before transplanting (late April), or direct sow after May 15 when soil temps are reliably above 65F. Most heirloom moschata varieties have 90-110 day maturity, so they need to be in the ground by early June at the latest for a fall harvest.
