Spiraea japonica ‘Crispa’ is a distinctive summer spirea prized for its finely toothed and slightly wavy foliage, which gives it a unique texture in the garden. This deciduous shrub develops a rounded, dense habit, wider than it is tall, ideal for borders, mass plantings, and foundation plantings. In summer, its corymbs of deep pink flowers generously cover the dark green foliage, creating an attractive contrast and attracting pollinators. Its crimped foliage sometimes takes on reddish hues in autumn, adding extra seasonal interest. Very hardy and easy to care for, Spiraea japonica ‘Crispa’ prefers well-drained soil and a sunny exposure to ensure abundant flowering and compact growth. It is an excellent choice for adding texture and color to northern landscapes.
