A small genus of 4 species of shrubs native to eastern Asia, that are closely related to the Spirea. They are grown mainly for their attractive foliage which emerges early in spring, remains lush green all summer, then turns vibrant colors in autumn.
They prefer full sun to partial shade on moist, acidic, light, fertile soil. A mulch with pine bark or pine needles will increase growth. Stephanandra's are very easy to grow and not all that fussy about soil.
Overgrown and straggly plants can be cut back hard in early spring to renovate.
Propagation is from softwood cuttings taken during summer, hardwood cuttings during winter or division in autumn.
