Family

Rosaceae

Botanical Name

Exochorda racemosa

Plant Common Name

Common Pearlbush

General Description

Showy clusters of large snowy blooms deck the arching branches of common pearlbush in mid-spring. This large, rounded, deciduous shrub is native to shady hillsides in eastern China.

The dull green, elliptic leaves of this hardy shrub emerge in early spring, shortly before the white, five-petaled, silver-dollar-sized blooms appear. The flowers are borne in 6- to 10-flowered racemes along the outer branches. Five-lobed, turban-shaped seed capsules follow the flowers. The capsules persist long after leaf-fall, adding winter interest.

Grow common pearlbush in full sun to light shade in deep, fertile, acidic to neutral soil. Tolerant of drought once established, this shrub requires little maintenance. Prune after bloom to remove any scraggly growth. This little-known shrub works well in large mixed borders and informal screens and hedges. It is a parent of the more compact and equally showy-flowered 'The Bride'.
