The ‘Greengage’ plum (Prunus domestica ‘Greengage’), a beloved European plum cultivar, is renowned for its exceptional sweetness and rich, honeyed flavor, often described as having notes of apricot and citrus marmalade. Despite its green to yellowish skin, it’s a mark of ripeness, indicating a highly concentrated sugar content. These relatively small, round plums have a dense, juicy, amber-colored flesh that’s often free-stone, making them perfect for eating fresh, canning, making jams, or baking into pies and crumbles. For abundant fruit production and the sweetest plums, ‘Greengage’ plum trees require a site with full sun, receiving at least 6-8 hours of direct sunlight daily. While they can tolerate some afternoon shade in very hot climates, full sun is crucial for optimal growth, flowering, and ripening of their highly prized fruit. They also benefit from well-drained soil and consistent moisture during fruit development.
