Spiraea is a genus of flowering plants in the family Rosaceae, commonly known as spireas. These deciduous shrubs are native to the Northern Hemisphere and are valued for their attractive clusters of small flowers, which can be white, pink, or red. They typically bloom in late spring to early summer and are often used in landscaping for their ornamental appeal. Spiraea species vary in size and shape, with some growing as low ground covers while others can reach heights of several feet. They thrive in well-drained soil and full sun, making them suitable for gardens and parks. Additionally, spireas are known for their hardiness and ability to attract pollinators like bees and butterflies.
