Sorbus intermedia (Swedish Whitebeam)
Sorbus intermedia (Swedish Whitebeam) is a medium-sized deciduous tree adorned with a broad, dense canopy of broadly oval, deeply-lobed, dark green leaves covered with gray hairs on the underside, giving the tree a silvery appearance. In late spring, a profusion of tiny white flowers held in flat-topped clusters are produced. They are quickly followed by abundant clusters of showy, bright red berries in late summer. The berries provide a welcomed feast for various types of weary, migrating birds and seldom last very long. It is often planted along streets in urban areas as a result of its tolerance to air pollution and ornamental value. It is also particularly suitable for exposed and coastal sites. Attractive in form, elegant in flower, colorful in fruit and foliage, Sorbus intermedia stars in almost every season of the year.
