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.

Oregon Grape is an evergreen shrub native to North America, found along the Pacific coast. In spring, the bright golden-yellow flowers appear in clusters above the leaves. These flowers eventually give way to edible blue berries in late summer. While not a true grape, the berries appear grape-like due to their colouring and clustered growth. They can be eaten fresh, but the sour taste and high amounts of natural pectin make them well suited for preserves.

The Oregon Grape has leaves that are glossy, leathery, and spiny-edged. This feature gives it its alternate name of Holly-leaved Barberry. When the leaves emerge in the spring they are a bronze-red colour. In the summer they transition to green, followed by bright red to deep burgundy in the fall. Leaves are retained throughout the winter and colder temperatures cause the leaves to turn purplish bronze, providing year round interest to the landscape.
