Noteworthy Characteristics

Exochorda serratifolia, commonly called pearlbush, is an upright, outward-spreading, thinly-branched, spirea-like deciduous shrub of the rose family that typically matures to 6-8' tall with a slightly wider spread. It is native to open woodlands, slopes and stream banks in northeastern China and Korea. Pearl-like buds (hence the common name of pearlbush) open in early spring (April-May) to an attractive bloom of star-shaped, 5-petaled, white flowers (to 1.5" wide) arranged in terminal racemes. Elliptic green leaves (to 3" long) have marginal teeth from the middle of each leaf to the apex. Leaves turn yellow in fall.

Genus name comes from the Greek words exo meaning outside and chorde meaning a cord referring to fibers outside the placenta in the ovary.

Specific epithet means leaves with a saw-tooth margin.
