Rhododendron Species Botanical Garden
Federal Way, Washington

This garden was established in Federal Way, on property leased from the Weyerhaeuser Company, in 1975 and opened to the public in 1980. It is a 22 acre display garden devoted almost entirely to Rhododendrons, with companion plants added to improve the aesthetic appeal.
The Rhododendrons are planted in beds based on taxonomy rather than geography, so species closely related to one another are planted together regardless of where they occur naturally. This is probably a really interesting arrangement for Rhododendron fanatics, but I’d find a geographic arrangement more interesting and informative.
