Exochorda

This group consists of a few very beautiful, hardy, deciduous shrubs native of north and central Asia. In late spring, their slender branches are clothed with large, snow-white flowers. These shrubs are commonly known as Pearl Bushes. E. racemosa (Common Pearlbush) is a large, spreading shrub with oblong, bluish-green leaves. In late spring, erect clusters of white flowers are produced. E. macrantha 'The Bride' is a small to medium-size, compact shrub that has a "weeping" habit of growth. Its arching branches are clothed with large, white flowers in mid- or late spring. E. korolkowii is an attractive variety that grows up to 15 feet high. It is suitable for growing in alkaline soil.

Pot Cultivation

Pearlbushes should be grown in full sun. They will grow in almost any garden soil, but prefer one that is on the acidic side. They tend to become chlorotic in very shallow, alkaline soil. After flowering, remove any weak stems and thin overcrowded ones.

PROPAGATION: Cuttings can be made from young shoots, 3 to 5 inches long. They will readily root in a propagating frame in July or August. Seeds can be sown under glass as soon as they are ripe. Suckers can sometimes be detached from older plants in the fall.
