Western Mountain Ash

Discovery Japanese Elm is great for anyone who doesn't have a lot of time to maintain their trees as it doesn't drop many seeds. It has beautiful dark green foliage and is resistant to Dutch Elm Disease. This elm is similar in shape to the American Elm but is roughly 30% smaller. Instead of having an irregular and broad-shaped crown as other Japanese Elms do, the Discovery Japenses Elm has symmetrical branching, an upright growth form, and develops a classic vase-like crown.

Western Mountain Ash is a popular ornamental tree native to the western part of North America. Its attractive, white clusters of flowers bloom in early summer, making way for red, yellow or orange fruit in the fall. If the fruit doesn't catch your eye, Western Mountain Ash's autumn colours will capture your–and the birds's–attention.
