Yellow Crookneck Squash

Cucurbitaceae

Native American heirloom dating to 1700s. Curved neck, bright lemon-yellow, bumpy/warty skin at maturity. Buttery flavor, meaty texture. Somewhat LESS SVB-susceptible than zucchini. Harvest at 4-6 inches before warts develop — skin toughens rapidly if overmature. Very short refrigerator life (3-4 days). Bush habit, compact (2 ft tall × 3-4 ft wide).
