Cotoneaster horizontalis var. perpusillus, commonly known as Rockspray Cotoneaster, is a deciduous shrub native to the rocky hillsides and forest margins of Western and Central China. It exhibits a moderate growth rate, reaching heights of 1-3 feet (0.3-0.9 meters) and spreading 6-8 feet (1.8-2.4 meters) wide. The plant is characterized by its distinctive herringbone pattern of branches and small, glossy green leaves. In late spring to early summer, it produces a profusion of small, pink flowers that are followed by bright red berries in the fall, which persist into winter and provide visual interest as well as food for birds.

Rockspray Cotoneaster is valued for its low maintenance, its ability to stabilize slopes and banks, and its use as a ground cover or in rock gardens. It is also suitable for bonsai. This plant thrives in full sun to part shade and adapts to a variety of soil types, including clay, loam, or sandy soils, provided they have medium to fast drainage. It requires moderate watering but can tolerate some drought once established. While it is generally disease-resistant, it can be susceptible to fire blight and scale insects. Due to its spreading habit, it can be invasive in some regions, so it is essential to consult local guidelines before planting it outside its native range.CC BY-SA 4.0
