Western Rhododendron Information


The western rhododendron is the state flower of Washington, a plant capable of growing under evergreen trees such as the Douglas fir and hemlock. The western rhododendron is typically a shrub but in some instances, it grows to the size of a small tree.


The western rhododendron grows along the area of the Pacific Coast from British Columbia southwards to the Monterrey region of California. It exists in the Cascade Mountains and thrives among many of the large trees that occur in this region.


In the majority of western rhododendrons, the plant is between 6 -12 feet tall, but some do make it to 25 feet in the open. The leaves are 3 - 6 inches long and as wide as almost 3 inches.


The flowers of this plant bloom from May into June, developing in clusters of as many as 15 to 20 pinkish flowers that contrast greatly with the dark green leaves.


The western rhododendron is the type of plant that a gardener can transplant from where it has become crowded into a more open spot where the plant will expand and flourish.


The Washington state legislature designated the western rhododendron, also called a coast or Pacific rhododendron, as the state flower. In 1892, the flower had been unofficially voted the state flower by women seeking to have a flower represent Washington at the 1893 World's Fair held in Chicago.
