Plant Common Name
European Mountain Ash, Rowan
European mountain ash is a small to medium-sized, rounded, deciduous tree native to Europe, Siberia and western Asia. It has also become naturalized in northern regions of North America--from Newfoundland to Alaska. Many features make it a showy landscape tree all season long, including its feathery, pinnately compound leaves, flat heads of musky-scented white spring flowers, fall clusters of vibrant red-orange berry-like pomes and vibrant fall leaf color that ranges from yellow to red or burgundy. The edible pomes are favored by birds, but may also be processed into a tasty, tart jelly that is eaten with poultry or game.
Plant the European mountain ash in full sun to partial shade and well-drained soil rich in organic matter. It grows best in slightly acid soils but will tolerate more alkaline soils. It also withstands strong winds, harsh winter cold and some summer heat. For best fall foliage color, water trees during substantial periods of summer drought. Plant in the landscape as a small shade tree or lawn specimen. Of the many noteworthy cultivars, 'Beissneri' has pretty coppery-brown bark and lobed leaflets, 'Carpet of Gold' bears sulfur-yellow to yellow-orange fruits, and 'Pendula' is an orange-fruited weeping form.
Be aware that several diseases and pests can be problematic, including scab, fireblight, various cankers and sawfly larvae. This tree is considered invasive in the Northwest United States and other areas.
