Begun in 2007, this garden is designed to provide a harmonious space to view the wide variety of rhododendrons that can be grown in the Pacific Northwest climate.

We introduce you to rhododendrons that bloom successively and whose foliage is varied and distinctive. These plants are lovely twelve months of the year with their beautiful spring blooms and evergreen foliage. The garden features rhododendrons that grow from a few inches to over twenty feet in height. Take time to observe the radiant bloom colors, as well as appreciate the great variety of leaf forms and colors. Two trees and a few snowdrops and daffodils provide contrast. In the wild rhododendrons are understory plants that love partial sun and shade. Although the small trees provide some shade here, our garden is in a sunny location so it contains rhododendrons with moderate to full sun tolerance.

A special feature of the Rhododendron garden is the espalier.  This variety of rhododendron is Rhododendron racemosum ‘Apricot’. Because the species is amenable to hard pruning, this attractive selection (Apricot) was chosen to train against a trellis. Annual pruning should be done in the spring after blooming to keep it flat against the trellis.

 

An excellent website for information about rhododendrons is The American Rhododendron Society.
