Culture
Best grown in moist, organically rich, well-drained soils in full sun to part shade. Tolerates urban conditions. Tolerates some droughty conditions. Good soil drainage is essential. An annual pruning immediately after flowering will encourage growth of new stems for better bloom the following year. Promptly remove root suckers unless naturalization is desired.
Noteworthy Characteristics
Prunus glandulosa, commonly called dwarf flowering almond, is a small, multi-stemmed shrub that typically grows to 4-5’ tall and spreads to 3-4’ wide. It has thin stems and an irregular form. Over time, it may open up and appear cosmetically unkempt, particularly if not pruned. Pink to white, single or double, cherry-like flowers (1/2”) bloom in mid-spring (April) along the stems. Flowers are followed by subglobose dark red fruits (3/8” in diameter). Pointed, serrulate, oblong leaves (to 4” long) are light green. No fall color.
Genus name from Latin means plum or cherry tree.
'Sinensis' is noted for its double pink flowers (each to 1 1/ 4” diameter) and shiny green foliage. Synonymous with and commonly sold as ‘Rosea Plena’.
Problems
Susceptible to a large number of potential insect and disease pests, often resulting in an abbreviated life span of less than 10 years. Fireblight can be a significant problem. Additional potential diseases include leaf spot, die back, leaf curl, powdery mildew, root rot and honey fungus. Potential insect problems include cankers, borers, Japanese beetles, aphids, scale, leafhoppers, caterpillars and tent caterpillars. Spider mites may also be troublesome.
