Overview
Mount Royal plum has been a reliable European plum variety for northern growers. It is an upright to spreading tree with an open center and moderate vigor.
Flavor and Uses
The light blue plums are juicy, semi-freestone, and have sweet flesh. They are excellent for fresh eating, okay for drying, and ripen in late August to early September.
Cold Hardiness
Mount Royal has survived temperatures as low as -44°F in West Central MN and -42°F in Columbus, MT, proving its hardiness in extreme conditions. UPDATE FALL 2025: We just discovered that Mount Royal has survived and borne a consistent crop in Lodgepole, Montana at MSU's Lodgepole Fruit Research Site, where it has gotten down to sub -45F temps.
Rootstock and Cold Tolerance
Our Mount Royal plums are grafted onto Native Plum, which is hardy to at least -50F. Native Plum is semi-dwarf in our MT climate/soils.
