Western Mountain Ash
Ironwood Tree

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.

Ironwood Tree is one of the strongest and most resilient trees you will find in North America. In fact, it has the hardest and most dense wood of any North American tree. Prized for its oval shaped canopy and showy winter trunk, this striking shade tree will make a beautiful addition to any yard. Make sure you do not plant near roads as it is highly salt sensitive.
