Prunus domestica ‘Shiro’, known as the 'Shiro' plum tree, is an early Japanese variety renowned for its abundant production of large, golden-yellow plums with juicy, sweet, and slightly tart flesh. Highly decorative, it boasts an abundant white bloom in spring, attracting pollinating insects and adding ornamental interest to the family orchard. Its vigorous rounded habit and moderate growth make it an excellent choice for edible gardens in Quebec, especially in sunny locations. Although self-sterile, ‘Shiro’ fruits abundantly if paired with another compatible plum variety. It tolerates fertile, well-drained soils well, and its hardiness adapted to our winters makes it a reliable variety. Thanks to its flavorful fruits and attractive blossoms, the 'Shiro' plum tree combines decorative value with generous production, perfect for small residential orchards.
