In short
- A profusely flowering shrub — in full bloom it almost disappears under pink flowers.
- Bell-shaped flowers with a yellow throat attract bees and bumblebees.
- Arching branches form a broad, fountain-like silhouette.
- Easy and hardy to USDA zone 4; tolerates chalky soil.
- Flowers on last year's wood — prune immediately after flowering.

Characteristics
The shrub reaches 2–3 m tall and is often even wider, forming a fountain-shaped clump with arching branch tips. The leaves are ovate and matt green. The small, bell-shaped flowers, with pink petals and a yellow-flecked throat, appear en masse in clusters; after flowering, small bristly fruits form. On older stems the bark peels away in strips, adorning the shrub in winter.
Growing and care
Watering
Fairly drought-tolerant once established. Water mainly in the first year and during prolonged heat; it does not tolerate waterlogging.
Fertilizing
Undemanding; a spring mulch of compost is enough.
Planting
A sunny site with free-draining, including chalky, soil; allow plenty of room for the broad, arching branches.
Pruning calendar
Pruning group: Spring-flowering shrubs
What and how to cut
Right after flowering each year, cut out 1/4–1/3 of the oldest shoots at the very base, and shorten the spent shoots back to a young side branch. This keeps a steady supply of young shoots coming from the bottom.
Immediately after flowering (June).
What not to do
Don't prune in winter or early spring before flowering — you'll remove the ready-formed buds and there will be no flowers. The right window is only the brief moment right after flowering. Don't shear them flat like a hedge either — you'll ruin the natural shape and the flowering shoots.
Companion plants
Good companions
They flower at the same time as the beauty bush and like a similar fertile, free-draining soil — together they make a classic May picture in shades of pink.
Both shrubs have arching branches and flower in pink in spring; planted together they reinforce the May effect in the border.
Bad companions
They need permanently wet soil, on which the beauty bush — adapted to dry mountain slopes — rots at the roots.
The evidence level indicates whether the relationship is backed by research, observation, or gardening tradition.

History and origin
The species was discovered in central China in the late 19th century and introduced to Europe and North America in the early 20th century by the famous plant hunter Ernest Wilson. The genus name honours the German botanist Richard Kolkwitz. As the sole member of its genus, beauty bush is a horticultural curiosity.
Uses
As a lawn specimen, for large shrub borders and naturalistic gardens. Because of its width and arching branches it needs plenty of room; it looks best planted singly, to show off its fountain-like habit.
Trivia
- The Latin amabilis means lovely, charming — hence the English name beauty bush.
- The peeling brown bark of older stems means the shrub adorns the garden even in the leafless season.
Frequently asked questions
Why is my beauty bush not flowering?
Usually because of pruning at the wrong time — beauty bush flowers on last year's wood, so pruning in spring removes the buds. Another cause is too much shade; the plant needs sun or bright partial shade.
How and when should beauty bush be pruned?
Immediately after flowering, in June. Each year, cut a few of the oldest stems out at the base to rejuvenate the shrub and encourage new, flowering growth. Do not shorten the shoot tips in spring.
How much space does beauty bush need?
It is a wide shrub, often spreading to 2.5–4 m, with arching branches that reach the ground. When planting it as a specimen, leave at least 2–2.5 m of free space on each side.
