Family

Rosaceae

Botanical Name

Spiraea betulifolia

Plant Common Name

Birchleaf Spirea, Spirea

General Description

A dwarf mounded deciduous shrub that possesses many similarities to Japanese spirea, this native of Northeast Asia bears flat heads of white flowers in late spring and early summer. The dense plants have purplish-brown stems. The small rounded leaves resemble those of birch.

Adaptable to a wide range of soils in sun and light shade, this is a highly versatile ornamental shrub that works well in mixed borders, foundation plantings, and rock gardens. Deadhead spent flowers to encourage prolonged secondary bloom. Prune back plants to a hand's-breadth and remove weak and dead stems in early spring to promote strong healthy new growth and larger more abundant flower heads.
