From "Fall"

Sorbus alnifolia/ Korean mountain ash

The foliage of Korean mountain ash is uniquely beautiful all through the year, but its most dramatic display is in autumn, when the leaves become bright orange. Bright berries in cherry-red to vermillion provide another part of the spectacular fall show of Sorbus alnifolia. The fruits are absolutely spectacular against the fall foliage and this tree's elegant, smooth gray bark.

Most Sorbus species are ravaged by root rots and show increased susceptibility to the many pests and diseases that already plague many of its rose family relatives; however, Sorbus alnifolia , a species from China, Japan, and Korea, stands far above the others in terms of trouble-free status. It also just happens to be one of the most striking trees in the fall landscape.

Korean mountain ash is a medium to large tree reaching 40 feet (12.4 m) in height with a 20-foot (6.2-m) spread. The crown becomes generously rounded as the tree matures from its oval habit in youth. Korean mountain ash has single, entire leaves, reminiscent of beech leaves ( Fagus spp.); many other Sorbus species have divided leaves similar to ash ( Fraxinus spp.) or pecan ( Carya illinoiensis ). The foliage of Sorbus alnifolia is beautiful all through the year, emerging a velvety emerald which darkens to a rich grass-green and finally colors dramatically in autumn. Korean mountain ash flowers in late spring, bearing flattened clusters of delicate white flowers. These flowers mature into the striking show of colored fruit, which the birds also seem to enjoy.
