Noteworthy Characteristics
Ural false spirea is a coarse, suckering, deciduous shrub which typically grows 5-8' tall (less frequently to 10') and as wide. Features tiny white flowers in dense, terminal, pyramidal panicles (to 10" long) in early summer. Compound, odd-pinnate, deep green foliage resembles that of mountain ash (Sorbus) to which it is related.
Problems
No serious insect or disease problems. Can spread aggressively by root suckers, particularly in loose soils (less invasive in heavy clay soils).
Garden Uses
Best for naturalizing in areas where it can be allowed to spread. Mass for erosion control on banks and slopes. Screens. Shrub borders.
