Black Diamond Watermelon
Heirloom. Black Diamond is a classic oblong watermelon with a black-green rind covering bright red, crisp, flavorful flesh. In the 1950s, Black Diamond was a very popular home garden variety. Fruits have gray-black seeds (perfect for seed spitting contests) and can grow quite large. In Arkansas, where it’s rumored to have been developed, local gardeners recommend this melon for greased watermelon contests: Simply grease the melon, place it into a child’s plastic swimming pool, and get ready for some fun as the kids chase it and try to grab it! Drought-resistant and prolific.
