This suckering shrub, native to Korea, Japan, China, and Eastern Siberia, is known as the False Spiraea (Sorbaria sorbifolia) because of the similarity of its white pyramidal flower panicles to those of Spiraea (steeplebush).
Sorbaria is a genus of around 9 species[1] of large hardy perennial shrubs that belong to the Rosaceae family. This flowering plant is sometimes referred to as ural false spirea or ash-leaf spirea.
They can reach a height of about 10 feet and bloom all summer, especially June through July. The flowers are conspicuous racemes of small white flowers in dense cone-shaped panicles 4-10 inches long.
Its compound leaves have pleasantly symmetrical rows of long, opposite leaflets. Its lush foliage and its absorbency make false spirea a choice for border and planting screens.
