Yoeme Segualca Squash is a butternut-type squash (Cucurbita moschata) collected from the indigenous Yoeme village of Vicam in Sonora, Mexico, near the Gulf of California. Its large, fluted fruits start mottled green and buff, ripening to a warm buff-beige, with an excellent, rich flavor that reflects its desert heritage. This cultivar thrives in hardiness zones 3 through 11 and handles moderate watering, making it adaptable across most of North America. Like other C. moschata varieties, it may need a long growing season to reach full maturity and develop its complex flavor.

These squashes command attention with their distinctive fluted shape and substantial size, shifting from mottled green tones to creamy buff-beige as they mature. The flavor is genuinely excellent, with a depth that comes from generations of cultivation in Sonora's challenging climate. Collected directly from the Yoeme people who have grown it for centuries, this is a living link to indigenous agricultural knowledge, preserved and shared through Native Seeds/SEARCH's Seed Bank Collection.
As a culinary squash, Yoeme Segualca is suited to roasting, pureeing for soups, and baking. Its excellent flavor makes it a standout choice for any preparation that showcases the squash itself rather than using it as a neutral ingredient. The dense, rich flesh works particularly well in traditional Mexican preparations and in autumn and winter cooking when long storage life and depth of flavor are valued.

Start seeds indoors 4 to 6 weeks before your last frost date, sowing them in warm soil between 70 and 85°F. Keep seedlings in strong light and warm conditions until they're ready to transplant.
Transplant seedlings outdoors after all frost danger has passed and soil has warmed to at least 70°F. Space plants 3 to 4 feet apart in rows that are 5 to 6 feet apart, giving them room to sprawl. Harden off seedlings gradually over a week before moving them to their final location.
Direct sow seeds outdoors after all danger of frost has passed and soil temperature reaches 70°F. Plant seeds 1 inch deep and thin seedlings to 3 to 4 feet apart once they've developed true leaves.
Harvest mature fruits when the skin has changed from mottled green and buff to a full buff-beige color, which signals ripeness. The stem should be dry and cork-like, and the skin should resist light puncturing with a fingernail. Cut squashes from the vine with a few inches of stem attached, and allow them to cure in a warm, well-ventilated space for 10 to 14 days before storage to harden the skin further.
