A large deciduous shrub that grows best in acidic, moist, organic soil. This plant is very low maintenance with attractive bell shaped flowers held in pendulous racemes and quite intense scarlet autumn foliage. Grows best in woodland areas, avoid dry hot areas. A plant worthy of its past awards and inclusion in the garden.

Description and Growing Information
Flowering Period
General Description
Enkianthus campanulatus is a deciduous shrub known for it's attractive, drooping, bell-shaped flowers.
Mass planting, screening, flower or autumn colour and as an accent.
Tolerant of some shade but must have soil conditions suited to azaleas and rhododendrons: a moist but free draining, acidic, humus rich media. Since it is a slow growing plant with a fibrous root system it is easily transplanted during its dormant period. Pruning should not be necessary and if severely cut back will take some time to recover. Believed to be one of the easiest to grow of its genus. The root system has minimal depth and can be improved with mulching.
Spreading, mound-shaped, bell-shaped flowers, leaves form a spiral shape on branches.

Easily by seed sown at 18 - 21°C. Also by layering fully developed branches in the summer months. Soft-wood cuttings are quite easy to root, collect 7.5 cm cuttings with a heal from lateral shoots in August and plant in a mixture of peat and sand, keep in a cold frame. Grow in a nursery bed for 2 - 3 years before planting outside. Tissue culture is now being used for some selections.
