This is quite a large genus of shrubs, ranging from a few trees to some very dwarf and/or prostrate alpines. They have small pink or white flowers, much visited by bees and other insects, and fruits that are usually red, which are valuable food for birds. Most species are evergreen, with shiny, deep green, small leaves, but there are also deciduous species, which tend to have larger, lighter green and less shiny leaves.

Cotoneaster forrestii is a deciduous shrub with an upright habit, with stems lined with deep green, glossy leaves. In autumn they turn purplish red. The red-pink flowers are followed in late autumn by orange red fruit, lining the long stems. It was once known as Cotoneaster nitidus var. duthieanus, but it is far better celebrating George Forrest.
