Exochorda serratifolia (Sawtooth Pearlbush)

Exochorda serratifolia, often known as pearlbush, is a spirea-like, erect, outward-spreading deciduous shrub of the rose family that grows to 6-8' tall with a somewhat larger spread. It is found in northeastern China and Korea in open woods, hillsides, and stream banks. Early in the spring, pearl-like buds open to reveal a showy display of star-shaped, 5-petaled white flowers grouped in terminal racemes. From the centre of the leaf to the tip, elliptic green leaves contain marginal teeth. In the fall, the leaves become yellow.
