General Culture:
Easily grown in average, medium wet, well-drained soils in full sun. Tolerates a wide range of soils. Remove faded flower clusters as practicable (light shearing is an option) to encourage additional bloom. Flowers on new wood, so prune in late winter to early spring if needed.
Noteworthy Characteristics:
Japanese spirea is a dense, upright, mounded, deciduous shrub that typically grows 4-6?tall with a slightly larger spread. Leaves (to 3?long) are oval and sharpely toothed. Tiny pink flowers in flat-topped clusters (corymbs) cover the foliage in late spring to mid-summer with sparse and intermittent repeat bloom often occurring throughout the remainder of the growing season. Flowers are attractive to butterflies. 慍rispa?is a compact mounded cultivar that grows to 2-3?tall and as wide. Deep pink flowers in flattened corymbs (to 3?across) appear in summer. Dark green leaves are twisted and crinkled, hence the cultivar name. Foliage often emerges with a reddish tint and some burgundy variegation may be seen in the mature foliage. Sometimes offered for sale by nurseries as S. x bumalda 慍rispa?
Problems:
No serious insect or disease problems. Susceptible to many of the diseases and insects that attact other rose family members, including leaf spot, fire blight, powdery mildew, root rot, aphids, leaf roller and scale.
Uses:
Specimen or group for rock gardens. Mass or group in shrub border. Low hedge for path and walkways. Incorporates well into foundation plantings.
