Beautybush

Kolkwitzia amabilis

The one and only species in the Kolkwitzia genus which is however related to the Weigelas and Deutzias. It is a rare native to the mountains of central China. The Beauty Bush is a fast growing, large shrub reaching up to 12 x 12 or rarely 20 x 20 feet with long arching branches. Some records include: 5 years - 6.5 x 6.5 feet; 10 years - 10 x 8 feet.
The tapered, broadly-oval leaves are up to 3 x 2 inches in size. The foliage is reddish at first, quickly turning to dull green then to dull red during autumn. The leaves are oppositely-arranged on the stems.
During late spring the shrub is covered in masses of medium-pink, bell-shaped flowers, up to 0.5 inches wide, with yellowish throats. The fragrant flowers are borne in corymbs ( clusters ) up to 3 inches wide.
Hardy zones 4 to 8 and very heat tolerant. Prefers full sun on fertile, well drained soil. Tolerant of limestone soils and temporary drought.
Beauty Bush is rarely bothered by pests or disease and is rabbit and deer resistant.
Pruning is typically nothing more than tidying up after blooming.
It is easy to turn a Beauty Bush into an ugly bush by shearing. This is NOT a hedge.
Only plant it where it has room to be itself. To renovate an aging shrub; simply cut to ground immediately after blooming; it will grow back.
Propagation can be from removed suckers or softwood cuttings taken late spring to early summer. Seed can be sown as soon as it ripens.
