"The Spiraea 'Japanese White', Spiraea albiflora, has bright green foliage, topped by heavy clusters of white blooms. This deciduous shrub is low growing and exhibits a rounded form. Japanese Whites are effective in mixed shrub plantings, low borders and clumped together. Spiraeas are covered with flat clusters of flowers in June and again off and on all summer, especially if the old flowers are pruned. Spiraeas are great in shrub groupings, near buildings, mass plantings, and low hedges."
