Mount Royal Plum on Myrobalan (Spring 2025)
An early, cold-hardy European plum.
This tree is cold hardy, tolerant of poor soils, and resistant to black knot. The habit is open-spreading. It is self-fertile, but for best results we recommend a second European plum for cross-pollination.
Ripening a week or two before Stanley, Mount Royal produces a prolific crop of small-medium round plums. The skin is blue and the flesh is firm, greenish yellow, and freestone. The flavor is very sweet and a bit spicy. These plums are suitable for fresh eating, drying, and processing.
Mount Royal was first cultivated in Montreal, Canada in the late 1700's.
