The classic Charleston Gray watermelon, known for its oblong shape, red, fiberless flesh, and tough, medium-thick gray-green rind suitable for making pickles, was once a staple in home gardens and markets. Originating from the USDA Southern Vegetable Breeders Lab in Charleston, South Carolina, in 1954, this variety is celebrated for its seed-spitting potential and requires ample space for vine growth. Esteemed as one of the best All-American watermelons, Charleston Gray delivers super-sweet, full-flavored red flesh in 20-40 lb fruits, yielding abundantly for both home and market use. Perfect for late summer barbecues and picnics, this open-pollinated melon developed by Charles Andrus boasts resistance to Fusarium wilt and anthracnose, with a greenish-gray rind that prevents sunburn. Affectionately known as "that gray melon from Charleston," it averages 22”–26” in length and weighs 25–35 pounds, not seedless, adding a historic touch to any garden.
