    • Description

      Mount Royal plum is a variety of European plum (P. domestica). It has dark green foliage throughout the season with leaves that turn yellow in fall. This tree is a self-pollinator. The flowers are white, showy, and fragrant. They bloom in the spring. Blue drupes are ripe in August and are sweet and tender. They can be eaten fresh, dried, or in baked goods. The dark green foliage turns yellow in the autumn. The expected average age is 40 years in ideal conditions.


      Mount Royal plum needs full sun and even soil moisture. It is tolerant of inner-city environments, soil types, and most pH levels. The fruit can be messy if it is not harvested. Maintenance is needed for this tree; pruning should be done in late winter after an extreme cold.


      It can be used in an edible landscape, orchard, under power lines, or as a specimen tree. Ideally planted as a stand-alone tree due to a wide-opening canopy. 


      The fruit of this tree will be sought after by birds and small mammals. 


      Be on the lookout for plum aphids, caterpillars, fruit tree red spider mites, brown scale, plum moths, bullfinches, silver leaf, bacterial canker, and brown rot.
