Spiraea japonica 'Anthony Waterer'

Dense, upright, mounded, deciduous shrub. Leaves are oval and sharply-toothed. New foliage emerges with reddish purple tinting in spring, matures to blue-green by summer and finally turns reddish in fall. Carmine red flowers in flat-topped clusters cover the foliage from late spring to mid-summer, with sparse and intermittent repeat bloom sometimes occurring. Flowers are attractive to butterflies. Hardy, prefers a sunny site.
