Spiraea is a genus of flowering plants in the family Rosaceae, commonly known as spireas. These shrubs are native to the Northern Hemisphere and are appreciated for their attractive clusters of small flowers, which can be white, pink, or red. Spiraea species are often used in landscaping due to their hardiness and ability to thrive in various soil types. There are over 80 species of spirea, with some popular varieties including Spiraea japonica and Spiraea alba. They typically bloom in late spring to early summer and can attract pollinators like bees and butterflies. Spiraea plants are also valued for their ornamental foliage, which can provide seasonal interest.
