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.

Buttonbush is a moisture loving shrub that provides year round interest.

It has round, fragrant flowers resembling small buttons or pincushions. The flowers transform into small reddish-brown fruit that persists into winter while the leaves take on shades of red in fall.

Providing essential food to bees, butterflies, and other insects, this shrub is versatile. Try it in your next shrub border.
