Originating from W. China
In maturity this species can form a wide-spreading crown with many horizontal branches low over the ground, exuding an ancient and romantic English country character with its billowing crown of blossom in spring. It has the best ornamental glossy copper/red bark of all prunus, peeling throughout the season to reveal ever glossier new layers. The papery exfoliations are especially attractive when backlit by the sun, as they glow a warm amber colour.
A tough and undemanding species, it grows well in all soils, producing the best foliage and flower displays in full sun.
