Watermelon Black Diamond is a prized heirloom variety celebrated for its exceptional sweetness and deep crimson flesh. These impressive melons develop a distinctive dark green, almost black rind with a thick skin that protects the juicy interior and extends shelf life. Non-GMO and open-pollinated, Black Diamond produces large, round fruits ideal for slicing fresh or serving at gatherings. This variety thrives in warm climates and delivers reliable yields when given full sun and well-draining soil. The melons mature in 70–80 days, making them suitable for most growing regions with adequate heat. Black Diamond's crisp texture and rich flavor make it a favorite among home gardeners and small-scale growers seeking authentic heirloom quality. Each seed packet contains 25 seeds, providing ample opportunity to establish a productive patch or share with fellow gardeners.
