Korean mountain ash

S. alnifolia is a large, deciduous tree up to 20m tall. Its upright branches form a neat, rounded canopy whilst its bark is unusual, being dark or pale grey, finely-striped in buff. Leaves are dark green, ovate, up to 9 x 6cm, on red leaf-stalks, and turning yellow in autumn. A proliferation of white flowers, 1cm wide, are produced in spring. Clusters of berries in autumn turn from orange to red and are held on the tree well after leaf fall
