Carpinus caroliniana 'Red Fall'

RHS Plant Profile
American hornbeam 'Red Fall'
Trees

A medium-sized, deciduous tree, with blue-grey bark that is smooth when young, but becomes fissured when older. The tree forms a wide conical crown and can reach 12m (40ft) in height when mature. The foliage emerges reddish, becoming green in summer as it matures, before becoming a fiery orange red in autumn. The green, male and female catkins are produced separately on the same tree in April. The female flowers after fertilisation, develop into hop-like clusters in late summer to autumn, containing winged seeds which disperse on the wind when ripe
