Japanese spirea is a deciduous shrub native to Japan and China, reaching 2-4 feet tall with small, lance-shaped leaves and flat clusters of pink to magenta flowers appearing mid- to late summer. The plant is compact and spreading.

Japanese spirea is hardy to zones 3-8 and thrives in full sun to light shade with well-drained soil and moderate moisture. It is fast-growing and responds well to pruning; regular pruning maintains shape and encourages dense bloom. Multiple cultivars are available with selections for flower color, foliage variegation, and compact size.
