Not all azalea species thrive in Oregon.
Of the 17 North American azalea species, only one grows naturally in Oregon. Oregon's only azalea is the Rhododendron Occidentale, commonly called the West Coast azalea. This species is difficult to grow outside of the Pacific Northwest and California. It flourishes in moist areas near creeks and in the foothills of Oregon and Washington. Does this Spark an idea?
Distribution
The West Coast azalea grows naturally in 9 of Oregon's 35 counties: Yamhill, Lincoln, Benton, Douglas, Coos, Curry, Josephine, Jackson and Klamath. These counties are all in the west and southwest parts of Oregon, away from the state's higher mountains. The elevation in these counties ranges from sea level to 9,000 feet. However, the majority of the area where azaleas grow ranges from sea level to 3,000 feet.
Sun and Soil
The West Coast azalea does best in slightly sunny to partially shaded areas. It flowers from May to June and can reach sizes of 6 to 10 feet in height and width. It requires moist, well-drained, humus-rich soil. It often grows in large masses among evergreen trees.
Azalea, Oregon
Azalea, Oregon, is a town in Douglas County named in recognition of the vast numbers of West Coast azaleas that grow in and around the town. It sits at 1,644 feet above sea level in a valley that features many creeks.
Rhododendron Occidentale Ethnobotany
The West Coast azalea is commonly used to produce hybrid azaleas, particularly when there is a desire for scent enhancement. The Pomo and Kashaya tribes in California used the West Coast azalea in decorative dance wreaths. The Modesse people used the flower as a poison antidote.
