Thornless Honey Locust makes an excellent shade tree with its lacy foliage and dappled shade. The leaves are honey-yellow, light and airy, providing interesting color and texture to your landscape. This variety is thornless, and the seeds and pods provide food for wildlife such as deer and squirrels.

The Thornless Honey Locust is tolerant of drought, various soil conditions, and even road salt.

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.
