Common Pearlbush

Exochorda racemosa (ek-so-KOR-da ra-see-MO-sa)

Family: Rosaceae Non-native Shrub (3-15 ft)

Pearlbush is a loose, upright, spring-flowering deciduous shrub in the rose family (Rosaceae). It is native to Central Asia, China and the Korean Peninsula. Several species have been recognized in the genus, but it is now regarded as having a single species (with four subspecies). The species epithet is Latin for "having racemes," which are the flower stalks. It grows well in sun and prefers rich, well-drained, acidic soil, although it does well in more average soil and will tolerate alkaline soils and partial shade. It has slender branches and tends to have a loose or unkempt appearance with age. Pearlbush is as broad as it is high, with a tolerance for heat and drought. The plant typically reaches a height of 10 feet but can go as high as 15 feet. It is a dependable, tough plant that leafs out early. It can become overarching and floppy, but it can be severely pruned to rejuvenate. However, because it blooms on the previous year's growth, you should wait until the current blooms are spent before pruning. It is reported to be invasive in some states but is not currently listed as such for North Carolina. It is an early-flowering shrub, which can be a valuable nectar source for insects. The plant is most suitable for borders, hedges or foundation plantings. Dwarf forms make excellent bedding plants. Once established, it has a reputation for being tough and adaptable, but choose its location wisely because its taproot can make transplanting difficult. Quick ID Hints : White, 5-petaled flowers; buds like pear-headed pins Leaves are mucronate and entire below the middle of the leaf Fruit is ridged, green-brown, top-shaped, dehiscent capsule Some leaves have serrate teeth above the middle of the leaf Insects, Diseases and Other Plant Problems: No serious problems.
