Spiraea japonica Anthony Waterer (Japanese Spirea)

Spiraea japonica ‘Anthony Waterer’ (Japanese Spirea) is a compact, broadly mounded, deciduous shrub with delicate, willowy, reddish-purple leaves in spring, maturing to blue-green as summer progresses. The foliage turns vibrant shades of yellow and reddish-purple in the fall. In late spring to midsummer, domed sprays of deep rosy-pink flowers grace the tips of the branches and contrast well with the unusual bluish foliage. Heat-tolerant, this flowering shrub is a terrific choice for the landscape.
