  • Cotoneaster is a genus of flowering plants in the rose family, Rosaceae, native to the Palaearctic region, with a strong concentration of diversity in the genus in the mountains of southwestern China and the Himalayas. They are related to hawthorns, firethorns, photinias and rowans. Depending on the species definition used, there are between 70 and 300 different species of Cotoneaster, with many apomictic microspecies treated as species by some authors, but only as varieties by others. The majority of species are shrubs from 0.5–5 metres tall, varying from ground-hugging prostrate plants to erect shrubs; a few, notably C. frigidus, are small trees up to 15 metres tall and 75 centimetres trunk diameter. The prostrate species are mostly alpine plants growing at high altitude, while the larger species occur in scrub and woodland gaps at lower altitudes.
