The flowers are small and gathered in dense clusters, which can be umbrella-shaped, grape-like, or in panicles. Each flower has five petals—white, pink, or reddish—and many stamens. The fruit forms as a group of small pods called follicles.

Spiraea grows wild across the temperate regions of the Northern Hemisphere, with the most species found in eastern Asia. The genus once included some herbaceous plants now placed in other genera. The name 'aspirin' comes from Spiraea, as salicylates were first isolated from a related plant once classified in this group. Many species have been cultivated for their attractive flowers.
