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.

Some Bonnie Plants varieties may not be available in your local area, due to different variables in certain regions. Also, if any variety is a limited, regional variety it will be noted on the pertinent variety page.

Black Diamond Watermelon is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Our vine took off like crazy and had the full trellis covered within just a few weeks and then it moved down the entire length of our fence. We harvested about 7 full melons, but there would have been more if our neighbors lawn service hadn't cut a vine off that had almost seven baby melons in it. Taste wasn't as sweet as a large traditional store bought melon but still satisfying enough.
