Crookneck Pumpkin

Cucurbita moschata (cucurbit)

Also known as: Pennsylvania Dutch Crookneck, Dutch Crookneck, Neck Pumpkin

An 1800s Pennsylvania Amish heirloom and the direct ancestor of the modern butternut. Distinctive long curving neck in pale tan, with all the seeds packed into the small bulb at the end — meaning the entire neck is pure, seed-free flesh, sweet and nutty with the same smooth-textured deep orange colour as butternut, just far more of it per fruit. A traditional winter keeper for Amish and Mennonite kitchens, prized for storing right through to spring. Vines are vigorous and productive — give them 3-4 metres of room, or train the sturdy stems up a strong trellis with slings for the fruit.

Days to harvest 120-140 days

Fruit size Up to 3kg — long curved neck with a small bulbous seed cavity at one end

Sowing depth 20mm

Germination 5-10 days at 21-35°C

Spacing 100cm apart in rows 250cm apart (vines sprawl 3-4m)

Aspect Full sun (part sun tolerated), fertile moisture-retentive soil

Frost tolerance Frost tender — grown as an annual; sow only after all frost risk has passed

Growing notes

Choose a sunny, sheltered spot with room to sprawl — vines will run 3-4 metres and can be trellised if space is tight (the necks curve naturally over supports and fruit needs a sling once it fills out). Position away from large trees that compete for water and nutrients. Watch for powdery mildew in humid weather — good airflow and morning-only watering help.

Soil preparation: A hungry feeder. Dig in generous compost and well-rotted manure before planting, and side-dress again when fruit starts to set. Aim for pH 6.0-6.8.

Support: Not needed for ground-grown vines beyond keeping developing fruit off wet soil (a tile or straw pad under each fruit prevents rot). For trellis growing, use a strong frame and sling each fruit in an old stocking or mesh bag once it's tennis-ball sized.

Harvest & cure: Cut fruit with 5cm of stem still attached once the vine dries off and the skin resists a thumbnail. Cure in a warm, dry, airy spot for 10-14 days to harden the skin, then store somewhere cool (10-15°C) and dry. Properly cured fruit keeps 6 months or more.

Short season tips

Crookneck needs a full 120-140 warm days to ripen — it's one of the longer-season pumpkins, so in cooler NSW areas start seeds in pots 3-4 weeks before your last frost and transplant carefully (cucurbits hate root disturbance — use biodegradable pots you can plant whole). Warm the soil under black plastic for two weeks before planting out to bring soil temperature into the 21°C+ range. If cool weather threatens before fruit fully cures on the vine, cut with a long stem and finish curing indoors somewhere warm and dry. In short-season areas, Waltham Butternut (a descendant) may be a more reliable choice.

Spring
Summer

Annual

Corn (classic "three sisters" trio) • Climbing beans (fix nitrogen, share the space vertically) • Nasturtium (trap crop for aphids and squash bugs) • Marigold (repels beetles and nematodes) • Borage (attracts pollinators, critical for fruit set) • Radish (trap crop for cucumber beetles) • Oregano (repels pests, ground cover)

Potatoes (heavy feeders, compete for the same nutrients) • Brassicas (cabbage, broccoli — compete heavily and attract different pests) • Other Cucurbita moschata varieties if seed saving (cross-pollination — will cross with Waltham Butternut) • Fennel (inhibits most vegetable growth) • Don't repeat in the same bed each season — rotate to break the squash bug and vine borer cycle

A traditional Pennsylvania Dutch/Amish heirloom dating from the 1800s, grown for generations by Amish and Mennonite communities across the American Northeast for its exceptional storage and cooking qualities. This variety is the direct ancestor of the modern butternut — Waltham Butternut and every commercial butternut you'll find today were bred down from Crookneck by selecting for smaller, more uniform fruit with the same seed-free neck.
