Watermelon Black Diamond is a prized heirloom variety celebrated for its exceptional sweetness, deep crimson flesh and weight around 30 to 50 pounds. 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. The open-pollinated genetics mean you can save seeds from your best-performing plants for future seasons, reducing long-term seed costs and allowing you to select for traits that perform well in your specific micro-climate. This self-sufficiency appeals to gardeners building sustainable growing practices. The thick rind also makes Black Diamond an excellent choice for storage and transport, holding quality for weeks when kept in cool conditions—a practical advantage for those planning larger harvests or farmers market sales. Each seed packet contains 25 seeds, providing ample opportunity to establish a productive patch, conduct succession plantings, or share with fellow gardeners. With proper spacing and consistent moisture during fruit development, expect yields of 4–6 mature melons per plant under optimal conditions.
