How to Grow Enkianthus

Sharing is caring!

Enkianthus is a medium to large deciduous shrub grown for its clusters of bell-shaped flowers and fall color. The creamy-white, red-veined, urn-shaped flowers appear in terminal umbels from mid-spring to early summer. The lance-shaped leaves turn from green to various shades of orange and red in autumn.

Enkianthus grows best in an open location. Plant it where the spring and summer flowers and fall foliage can be enjoyed up close. The silhouette of Enkianthus bare stems can be enjoyed if set against an evergreen background.

Enkianthus grows best in humus-rich, acid soil in full sun or partial shade. It has most of the same requirements needed to grow rhododendrons or azaleas.

The Enkianthus genus contains about 10 species of primarily deciduous shrubs and trees.
