Origins and History
Green Gold Squash is an heirloom variety belonging to Cucurbita maxima, a species long cultivated by Indigenous peoples of the Americas. While C. maxima traces back thousands of years to South America—especially regions of Peru, Bolivia, and northern Argentina—this particular variety, with its rich green rind and golden flesh, was stewarded by small farmers and seed savers in the 19th and early 20th centuries. Its heirloom status reflects a lineage preserved for its flavor, adaptability, and productivity before modern hybrids dominated commercial seed catalogs. Originally released in 1939 by the Minnesota Experiment Station, Green Gold Squash stands as part of the tradition of diverse, locally adapted winter squashes passed down through generations.
Thru the Northeast, Central, Midwest, and Northern Plains, the Buttercup squash quickly rose in fame after its release in 1932. But, like many well-bred open pollinated varieties, seed stocks of Buttercup "threw" variations, allowing other farmers and breeders a chance to adapt something even better. "Greengold" winter squash was derived from orange-rinded variants, bred forward by the Minnesota Experiment Station and released in 1939. As the name suggests, the skin is a deep orange base streaked with green. Fruits exposed to more sun will be more full orange, while those more hidden by squash foliage will have more green streaks.
In 2004, seed saver Heron Breen received a small seed sample from the "deep freeze" collection of the USDA GRIN seedbank at Fort Collins, Colorado. Green Gold winter squash had been long forgotten for no good reason. After years of careful seed increase, Mr. Breen makes this variety available again to the public thru the Ujaama Cooperative Farming Alliance.
Appearance and Characteristics
This variety produces medium to large fruits with a deep green rind, often mottled or flecked with lighter shades, giving it its “green gold” name when paired with the bright, golden-orange flesh inside. The skin is firm and thick, making it an excellent keeper through the winter months. Plants are vigorous, with sprawling vines that can cover large areas. The flesh is dense, fine-grained, and richly colored, offering both sweetness and a creamy texture after cooking.
According to the grower Herron Breen, the flesh is sweet and deep orange, and much more dry in texture than then sticky smooth Buttercup; nearly a Kabocha type in quality! Another unique (for today's eaters and gardeners) is the thin rind of this now rare variety. While nowhere near as impervious as a Hubbard, Greengold's rind defends against deer, mice, light early frosts, and rough handling at harvest. While giving way quickly to a sharp knife, this hard-shell characteristic helps Greengold keep much longer than its Buttercup parent.
Culinary Uses
Green Gold Squash is highly versatile in the kitchen. Its sweet, nutty flavor makes it excellent for roasting, baking, or pureeing into soups. The fine-grained texture holds up well in stews and curries, while its natural sweetness shines in pies, breads, and custards. When simply baked or steamed, it provides a nourishing side dish, and its long storage potential makes it a reliable winter food staple. Its bright color and depth of flavor often rival that of buttercup or kabocha types.
Growing Tips
Green Gold Squash thrives in warm-season gardens across USDA Zones 3–10, though it performs best in Zones 4–9. Direct sow seeds once the soil has warmed to at least 65°F, typically after the danger of frost has passed. Sow seeds 1–1½ inches deep, spacing them 3–4 feet apart in rows or hills, with plenty of room for the vines to sprawl. For shorter growing seasons, start indoors 3–4 weeks before transplanting. Squash prefer rich, well-drained soil amended with compost and benefit from consistent watering during fruit set and growth. Mulching helps retain moisture and suppress weeds.
Harvesting Guidance
Green Gold Squash requires a long season of 90–110 days to maturity. Fruits are ready to harvest when the rind has hardened and resists puncture by a fingernail, and the stem has begun to dry and turn corky. Cut fruits with several inches of stem attached to extend storage life. Cure squash in a warm, dry, and well-ventilated location for 10–14 days before moving to cool storage. Properly cured, Green Gold Squash can last several months, carrying its golden sweetness deep into winter.
