Spiraea japonica (Japanese Spirea) is a dense, broadly mounded, deciduous shrub with oval to lance shaped, sharply-toothed, bright green leaves. In late spring to midsummer, domed sprays of white to pink flowers grace the tips of the branches and contrast well with the foliage. The blossoms are followed by small capsules that are smooth and glabrous. A single plant produces hundreds of small seeds that are naturally dispersed. Heat and drought tolerant, Japanese Spirea is a popular ornamental shrub that is often grown as a flowering hedge, low screen, or foundation shrub.
