Japanese spiraea
Spiraea japonica
Japanese spiraea is a compact, deciduous ornamental shrub prized for its clusters of pink to magenta flowers in summer and attractive foliage that ranges from gold to green depending on the cultivar. It adapts well to a variety of well-drained soils and benefits from annual pruning after flowering to maintain a tidy shape and encourage vigorous new growth. Note that it is considered invasive in parts of North America, so check local regulations before planting.
