Cut-leaved Rowan A cultivar of the native Irish rowan or mountain ash, Sorbus aucuparia Asplenifolia is a medium-sized tree of symmetrical, upright habit. Umbels of creamy-white flowers appear in April–May, followed by large clusters of orange-red berries, which hold well on the tree, in late summer. The mid-green leaves are heavily cut, almost fern-like, and turn yellow-brown in autumn. An undemanding tree, which tolerates pollution and wind. Makes a good specimen or avenue tree. Excellent for wildlife, both pollinators and birds.
