Exochorda sp. or Pearlbush is a large shrub or small tree native to Central Asia, China and grows to a size of 5-10 feet tall if pruned regularly. This ornamental deciduous plant blooms profusely and produces white or off-white flowers during spring. It requires full sun and regular watering in order to thrive and prefers moist soils.
Pearlbush can be grown outdoors in USDA Zone 4-8. The best way to grow a Pearbush in cold regions is to plant it in a pot. Choose a container that is large enough to allow adequate spacing between the roots, and fill it with a good quality potting soil that is rich in organic matter. Place the pot in a location that receives full sunlight and water it regularly. Placing the pot in a sheltered spot gives it additional protection against extreme temperatures. Feeding with a balanced fertilizer once every two weeks during summer will ensure vigorous growth. During winter, apply a layer of mulch around the pot to protect the roots from extreme cold.
With proper care, Pearbush makes a beautiful addition to any garden. It provides year-long interest, with attractive foliage in summer and bright flowers in spring. Its bright blooms are sure to add a touch of elegance to any landscape.
