Charleston Gray is a classic oblong watermelon with red, fiberless flesh. Its tough, medium-thick gray-green rind is useful for watermelon rind pickles, so the harvest can have more than one job in the kitchen.

This is a seeded variety, once common in home gardens and markets. This variety originated in 1954 at the USDA Southern Vegetable Breeders Lab in Charleston, South Carolina. Give the vines plenty of room to run—and keep a seed-spitting contest in mind if that is your sort of summer entertainment.
