Cushaw Green-Striped Pumpkin: Growing the Southern Heirloom in Kansas
By Autumn Prairie Pumpkins
The Cushaw Green-Striped is one of those old Southern varieties that your grandmother probably grew if she grew anything. It's been a fixture of gardens across the American South for over 200 years, a big, dramatic crookneck pumpkin with pale green and white stripes that looks like nothing else in the patch. And it bakes into a pie that'll make you rethink everything you thought you knew about pumpkin pie.
Cushaws are Cucurbita moschata (some older sources may list them as Cucurbita argyrosperma, but the green-striped Cushaw widely available today is moschata), which gives them natural vine borer resistance, a must-have trait for Kansas gardens. They're big, they're productive, and they've been feeding Southern families through hot, humid summers for generations. Kansas summers aren't that different.
Why Cushaw Green-Striped Belongs in Kansas Gardens
Heat tolerance is baked into this variety's DNA. The American South and central Kansas share brutal summer heat, and Cushaw handles it without flinching. The thick moschata stems shrug off vine borers. The large, vigorous vines produce abundantly even in tough conditions.
The crookneck shape is distinctive, fruits typically weigh 10–20 lbs with a long curved neck and a bulbous seed end. The neck is entirely solid flesh, which makes processing easy: slice the neck into rings, peel, and you've got consistent pumpkin pieces without dealing with a seed cavity.
Kansas State University recommends moschata varieties for vine borer resistance. Their K-State's squash vine borer guide (MF3309) provides solid cultural guidance for growing pumpkins in Kansas conditions.
How to Grow Cushaw Green-Striped in Kansas (Zone 6b)
When to Plant
Direct sow mid-May after soil is 65°F or warmer. Plant 1 inch deep, 2–3 seeds per hill. Cushaw germinates quickly in warm soil. You can start indoors 3 weeks ahead, but direct sowing works well given the long warm season Cushaw needs (100–115 days to maturity).
Spacing
These vines get big. Space plants 8–10 feet apart with rows 10 feet apart. Cushaw is not a variety for small gardens, it wants to run. If space is limited, train vines along a fence line or the edge of your property. The vigorous growth is part of the charm, but plan for it.
Soil and Fertility
Rich, well-drained soil with generous compost. pH 6.0–6.8. Heavy feeder, work in 3–4 inches of compost and apply balanced fertilizer at planting. Side-dress with nitrogen when vines take off. Cushaw produces large fruit, so consistent fertility is important for full-sized harvests.
Watering
Deep, consistent watering, 1.5–2 inches per week during fruit development. Drip irrigation at the base is the way to go. The large leaf canopy will wilt on hot afternoons, that's normal heat response, not necessarily a water deficit. Check soil before irrigating.
Pest and Disease Management
Vine borer resistance is strong. The main pest concern is squash bugs, monitor leaf undersides for egg masses. Powdery mildew may appear late season but rarely affects fruit quality. The vigorous vines tend to outgrow most pest damage.
Harvest and Storage
Harvest when the skin is fully colored (cream and green stripes should be distinct), hard, and the stem is corky. Cut with 4 inches of stem. Cure for 10–14 days in a warm, dry area. Cushaw stores well, 3–5 months under proper conditions. The thin skin means it won't store quite as long as thick-skinned varieties like Dickinson, but it's still a solid keeper.
Cushaw in the Kitchen
Southern cooks have been making Cushaw pie for centuries. The flesh is light orange, mild, and slightly sweet, it makes a more delicate pie than the deep-orange moschata varieties. The classic Appalachian Cushaw pie is lightly spiced with cinnamon and nutmeg, letting the squash flavor come through.
The long crookneck makes this one of the easiest pumpkins to process, slice the neck into rings, peel, and cube. No wrestling with a seed cavity until you reach the bulb end. Great for soups, roasting, mashing, and pumpkin butter. Some Southern cooks also fry Cushaw slices like you'd fry apples.
Saving Seeds
Cushaw Green-Striped is open-pollinated and grows true from saved seed. Let one fruit mature fully on the vine. Scoop seeds from the bulb end, rinse, and dry for 2–3 weeks. Store in paper envelopes. Will cross with other Cucurbita moschata, isolate for seed purity.
