Sorbus sargentiana (also called Sargent's rowan and Sargent's mountain ash)







General description

Deciduous, hardy ornamental tree with open habit, large leaves and large bunches of red berries in autumn. Sorbus sargentiana is not a vigorous grower and is suitable for smaller gardens, giving shade in summer and autumn colour. This tree is also known for its sticky buds in winter, which can make it easy to confuse with a young horse chestnut if you are not familiar with the different winter shapes of trees. The specimen above was planted in 1983 at the Oxford University Botanic Garden.


The flowers attract flying insects and the fruits are attractive to birds, especially thrushes and blackbirds.
