The blackberry plum a hybrid or descriptive term features deep purple-black skin with juicy, reddish flesh, blending the sweetness of plums with blackberry-like tartness. Smaller than typical plums, they offer a complex flavor—earthy, floral, and slightly tangy—perfect for fresh eating or jams. Packed with vitamins C and K, plus antioxidants, they support immunity and heart health. A rare seasonal gem, ideal for gourmet desserts, preserves, or bold fruit salads.
