Spiraea Crispa This lovely variety has curious twisted green leaves and pink flowers in summer grows to about 50 cm on most soil types.
Spiraea GoldFlame Both the foliage and the flowers make this an interesting and colourful shrub. The foliage emerges each spring with a burnished bronze-red flush, but as the leaves mature they turn bright yellow, then luminous green. In mid- and late summer, clusters of dark pink flowers appear, seemingly backlit by the glowing foliage. Compact and easy to grow, it makes an excellent informal, low hedge or groundcover plant for a sunny well-drained border.
Spiraea Gold Mound is a deciduous shrub that is prized for its bright golden leaves in spring, which turn a brilliant yellow in autumn. Other shrubs may give you better flowers or more striking fall foliage, but this one excels in spring foliage. It is named for its gold leaves, of course, but also for its mound-like habit: It matures at 2 to 3 feet tall and 3 to 4 feet wide.
