Plant Profile: Cotoneaster horizontalis

Rockspray cotoneaster is a robust, densely branched shrub that grows slowly, typically reaching heights of 2 to 3 feet and spreading 6 to 8 feet wide. In warmer climates, it can be semi-evergreen or fully evergreen. This plant thrives in well-drained soil and is capable of withstanding poor soil conditions, preferring full sun to partial shade.

In spring, it produces an abundance of vibrant red fruits, while its reddish-purple foliage in the fall adds visual appeal, especially in regions where it sheds its leaves. The distinctive fishbone pattern of its branches ensures it remains an interesting feature throughout the year.

Commonly found in rock gardens, it is also suitable for slopes or rock walls and can be trained to grow along walls, trellises, or fences.
