Plum, Black Ruby (Prunus salicina ‘Black Ruby’) Black Ruby is an early-ripening Japanese plum known for its stunning dark reddish-black skin, bright red flesh, and sweet, tangy flavor. This plum ripens in mid to late June, making it one of the earliest stone fruits of the season. The fruit is medium-sized, firm, and juicy, with a flavor profile that's well-balanced — sweet but with a bit of zip — perfect for fresh eating, baking, and preserves. Vigorous and partially self-fertile, Black Ruby performs best when paired with another Japanese plum like Methley or Santa Rosa. It is well-suited to warm climates and thrives in USDA Zones 6–9, making it a good choice for growers in the South and lower Midwest. Its early white blossoms attract pollinators, while its manageable tree size and early harvest make it a valuable addition to food forests, orchard guilds, and permaculture systems that prioritize succession planting and diverse, low-input production.
