Cherry Plum

Prunus cerasifera (PROO-nus se-ra-SEE-fer-uh)

Family: Roseaceae Non-native Understory (15-40 ft)

The purple leaf plum or cherry plum is a medium-sized, ornamental, deciduous tree that is typically short-lived. The tree is upright and twiggy with a rounded to vase-shaped crown and brittle wood. Small, fragrant, pure white, 5-petaled flowers with numerous stamens bloom in the spring as the leaves emerge. The leaves are green, ovate, or elliptic with serrated margins. Fruits, if produced, are cherry-like yellow or red and very attractive to birds. Varieties or cultivars of this species have deep reddish purple foliage and flowers of pale pink or lavender. The unique feature of these cultivars is that the leaves retain the purple color until they drop in the fall. The purple leaf plum is native to southeast Europe, Central Asia, and the Himalayas. It currently only exists in cultivation except where it has escaped gardens and naturalized. In the United States, this tree has naturalized in portions of the northeast and far west. The genus name, Prunus , is Latin and means plum or cherry. The epithet, cerasifera, is derived from two Latin words, cerasus , meaning cherry tree, and ferre , which means to bear. This tree flowers best in full sun but will tolerate partial shade. It requires moist, well-drained, loamy soils; however, it is adaptable to many soil conditions. Due to the structure of the tree and its brittle wood, it may be short-lived. When purchasing this tree, the specimen must have a good central leader. If the tree is pruned and well-cared for it may live 60 to 80 years. The species is not usually found commercially and is not typically used as an ornamental; however, there are many varieties and cultivars available for purchase. The purple-leaved and pink-flowered cultivars are very popular with many gardeners because of their ornamental value. Most years, these ornamental trees produce little or no fruit. The purple-leaved cultivars are best used as a specimen in the home landscape, and their foliage adds three-season interest. This spring small flowering tree is a great addition to a Japanese garden, butterfly garden, or cottage garden.
