The Mariposa plum is a Japanese-style plum variety prized for its large, heart-shaped fruit with deep reddish-purple skin and juicy, sweet, dark red flesh. Developed in California, Mariposa plums are known for their excellent flavor and attractive appearance. They are ideal for fresh eating, desserts, and preserves. The tree produces beautiful white blossoms in spring and typically requires another Japanese plum variety nearby for cross-pollination and optimal fruit set. Mariposa plums ripen in mid to late summer and are a favorite among home gardeners and orchardists.
