Spiraea Neon Flash
Spiraea japonica, commonly called 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 sharply-toothed. Tiny pink flowers in flat-topped clusters (corymbs) cover the foliage from late spring to mid-summer, with sparse and intermittent repeat bloom sometimes occurring. Flowers are attractive to butterflies. Species is uncommonly sold by nurseries because of the availability of numerous cultivars which are considered to be superior landscape plants. Most cultivars grow smaller (2-4' tall). Genus name comes from the Greek word speira meaning wreath in reference to the showy flower clusters seen on most shrubs in the genus. Specific epithet means of Japan, which is part of its native range.
