South Anna Butternut: Growing the Virginia Heirloom in Kansas
By Autumn Prairie Pumpkins
South Anna Butternut takes its name from the South Anna River in central Virginia, where this heirloom variety has been maintained by family seed savers for generations. It's a classic butternut shape, tan skin, bell-shaped with a curved neck, but with a reputation for exceptional eating quality that sets it apart from standard grocery-store butternut. The flesh is denser, sweeter, and more flavorful than most commercial butternut varieties, with a depth of flavor that only comes from decades of selection by people who actually cooked and ate what they grew.
As a Cucurbita moschata, South Anna Butternut brings the vine borer resistance that Kansas gardeners need. It's a solid, reliable producer that handles heat and produces beautiful, uniform fruit. If you love butternut flavor and want something with more character than Waltham, South Anna is an excellent step up.
Why South Anna Works in Kansas
Virginia's climate, hot, humid summers with ample rainfall, has shaped this variety into a heat-tolerant, disease-resistant plant. Kansas summers are drier but equally hot, and South Anna adapts well. The moschata vine borer resistance is reliable. Days to maturity run 95–110 days, fitting comfortably into our Zone 6b season.
Fruits are medium-sized (4–8 lbs), making them manageable for home kitchens. The plants produce well, expect 3–5 fruits per vine under good conditions.

How to Grow South Anna Butternut in Kansas (Zone 6b)
Starting Seeds
Direct sow mid-May, 1 inch deep, 2–3 per hill. Thin to strongest. Indoor starts 3 weeks ahead give an earlier harvest. Germinates well in 65°F+ soil.
Spacing
5–6 feet between plants, rows 7–8 feet apart. Semi-vining habit, more compact than full-vine types. Good fit for medium-sized gardens.
Soil and Fertility
Well-drained, compost-enriched soil. pH 6.0–6.8. Moderate feeder. Balanced fertilizer at planting, one side-dressing when vines run.
Watering
1–1.5 inches per week. Drip irrigation preferred. Consistent moisture through fruit set, then reduce as fruits mature.
Harvest and Storage
Harvest when the skin is uniformly tan and hard, stem dry and corky. Cut with 2–3 inches of stem. Cure 10–14 days in warm, dry conditions. Stores 4–6 months. Flavor improves with 3–4 weeks of storage.
South Anna in the Kitchen
This is a butternut variety that shines in simple preparations. Halve and roast at 375°F for 40–50 minutes, the flesh comes out silky, sweet, and rich. It's outstanding in soup, risotto, and pasta dishes. The denser flesh means less water content, which translates to more concentrated flavor in every dish.
South Anna also makes excellent pumpkin pie (butternut pies are actually one of the best-kept secrets in baking). The natural sweetness means you can reduce the sugar in most recipes.
Saving Seeds
Open-pollinated heirloom. Save seeds from fully mature, well-cured fruit. Scoop, rinse, dry 2–3 weeks. Cross-pollinates with other moschata. This variety exists because someone in Virginia thought it was worth saving, keep that tradition alive.
