Mountain Ash (Sorbus scopulina) is a gorgeous, deciduous, upright shrub or, rarely, a small tree that isn't actually a true Ash at all, but a member of the Rose family. Attractive, dark green, shiny, compound foliage appears on the shrubs multiple stems in spring. By late spring to early or mid summer, the entire plant is covered in clusters of showy, white flowers, which give way to ball-shaped red fruits that continue the visual interest of the plant. These berries are a food source for birds and other animals in the winter, but can also be harvested and used in syrups, jellies, and jams. They are generally very tart and best harvested after several frosts have improved their quality and taste. Foliage will turn brilliant shades of red or orange in the fall. Add Mountain Ash as a background or speciman plant in garden beds or borders, near the edges of woodland or shade plantings, or use in mixed hedges, privacy screens, or windbreaks. It will do best with consistant moisture and full sun to light shade. Remove suckers at the base as a part of yearly maintenance or place in an area where it can spread to form a hedge or screen.
