Features & Attributes
Mount Royal Plum is draped in stunning clusters of fragrant white flowers along the branches in early spring before the leaves. It has dark green deciduous foliage. The pointy leaves turn yellow in fall. The fruits are showy blue drupes with purple overtones, which are carried in abundance in late summer. The fruit can be messy if allowed to drop on the lawn or walkways, and may require occasional clean-up.
This is a deciduous tree with a more or less rounded form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition. This plant will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics.
Aside from its primary use as an edible, Mount Royal Plum is sutiable for the following landscape applications;
- Accent
- Orchard/Edible Landscaping
Planting & Growing
Mount Royal Plum will grow to be about 20 feet tall at maturity, with a spread of 20 feet. It has a low canopy with a typical clearance of 4 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more. This variety requires a different selection of the same species growing nearby in order to set fruit.
This tree is typically grown in a designated area of the yard because of its mature size and spread. It should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It may require supplemental watering during periods of drought or extended heat. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid.
