Snow Storm™ spiraea gets its name from the abundant clusters of pure white flowers that cover this mounded shrub in late spring. The blue-green leaves turn orange-red in fall. This shrub blooms on new wood so may be pruned in later winter if needed.

The genus Spiraea consists of small- to medium-sized flowering shrubs with a fine-textured twiggy mounding habit. The small, simple leaves are generally lance-shaped and held close to the branch. Spring to early summer abundant blooms tend to be in white or pink tones, depending on the species and/or cultivar. While individual flowers are quite small, they occur in clusters of inflorescence that can be very showy.

Spiraeas are best used in groupings in a shrub or mixed border, where they are valued as tough, reliable, and easy-care performers in northern climates. The Chicago Botanic Garden's collection includes nearly 100 varieties and 3,000 plants.
