beautifully veined mountain ash

S. caloneura is a large shrub or small tree, up to 12m tall in the wild, 4-5m tall in cultivation, with erect stems and wide-spreading branches in a flat-topped, tiered crown. The doubly-toothed simple leaves appear in early spring, or even late winter, and are at first bronze-tinted before becoming green and then turning golden-orange in autumn. Dense clusters, 5-8cm across, of clear white flowers with pink-purple anthers appear in early summer, followed by rounded or pear-shaped brown fruits, about 1cm long, in late summer and early autumn
