- Description
-
Rockspray cotoneaster is a coarse, dense, slow-growing, shrub that reaches 2-3 feet tall and 6-8 feet wide. In its southern reaches, it is semi-evergreen to evergreen. It requires well-drained soil and tolerates poor soils in full sun to part shade.
Spring blooms give way to abundant showy red fruits. The reddish-purple fall colors are attractive in areas where it is deciduous. The unusual fishbone branch pattern provides year-round interest.
Typically used in rock gardens, on slopes or rock wall and can be trained to walls, trellises or fences.
