Family

Rosaceae

Botanical Name

COTONEASTER horizontalis

Plant Common Name

Rockspray Cotoneaster

General Description

This is one of the prettier garden cotoneaster. This sprawling, deciduous shrub has herringbone-like branches that are attractive all season. Chinese in origin, it has small, round, dark green leaves that turn terrific shades of orange and red in fall. While each not individually impressive, it produces hundreds of pinkish-white flowers in late spring. The pretty berry fruits that follow turn bright red in fall and linger into the winter until they are eaten by birds.

Rockspray cotoneaster can withstand practically any well-drained soil. It grows best in full sun but will tolerate lightly shade. Established plants are quite drought tolerant and withstand Oceanside conditions. Prune selectively if at all. Many a rockspray cotoneaster has been destroyed by overzealous gardeners with pruners in hand. The plants naturally develop interesting, tiered branches with herringbone patterns.

If planted in groups along hillsides or in big beds, this cotoneaster creates quite a statement in the landscape. It is also suitable as a specimen for foundation plantings and can even be espaliered against walls. All are susceptible to fireblight and other fungal diseases that commonly plague rosaceous plants.
