Cotoneaster horizontalis (Rock Cotoneaster)

Slow-growing, Cotoneaster horizontalis (Rock Cotoneaster) is a spreading, deciduous shrub with flat and stiff, regularly-branched sprays in a strict herring-bone pattern. The branches are studded with small, glossy leaves that turn orange and red in fall. Small, 5-petaled, pink-tinged white flowers are produced in late spring. Attractive to bees, they are followed by brilliant scarlet berries which ripen in late summer to fall and provide one of the most cheering sights in the garden.
