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. ‘Gold Mound’ is, as the cultivar name suggests, noted for its attractive golden foliage. It is cross between S. japonica ‘Alpina’ and S. japonica ‘Goldflame’ (parents originally described as S. japonica var. alpina and S. x bumalda‘Goldflame’). Leaves emerge golden in spring, but gradually fade to a gold-green as the summer progresses. Fall color may include interesting yellows, oranges and reds. This is a compact mounded cultivar that grows to 42” tall and to 48” wide. Small pink flowers in flattened corymbs (to 3” across) appear in late spring.
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.
Mass or group in shrub borders. Low hedge for paths and walkways. Incorporates well into foundation plantings.
