Cotoneaster frigidus, the tree cotoneaster, is a species of flowering plant in the genus Cotoneaster of the family Rosaceae, native to the Himalayas. It is a deciduous tree or shrub growing to 10 metres (33 ft). White flowers are followed by masses of small, globose, red fruits (pomes) in autumn, persisting into winter if not eaten by birds. Cotoneaster frigidus ‘Cornubia’ is one of the largest cotoneasters, often forming an enormous bushy shrub but it can easily be trained into a standard to make a handsome tree with graceful branches that bend beneath the weight of fruit. Flowering is spectacular, the white open booms clustered densely in flattened heads, while the berries which follow are among the largest in the genus, pea-size and a conspicuous shade of vivid red in autumn and all winter. The flowers are a magnet for bees and the berries are eaten by birds. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).Cotoneaster 'Cornubia' is known for attracting bees, birds and other pollinators. It has nectar/pollen rich flowers, provides shelter and habitat and has seeds for birds.
