Rhododendron macrophyllum aka California Rose Bay

Rhododendron macrophyllum, also known as the Pacific rhododendron, California rosebay, California rhododendron, coast rhododendron, or big leaf rhododendron, is a large-leaved evergreen shrub native to the Pacific Coast of North America. This species, which is the state flower of Washington, typically grows 2-4m tall and has an upright, branching habit. Its dark green leaves are elliptic and can reach up to 15cm in length. In late spring, Rhododendron macrophyllum produces clusters of 20 or more bell-shaped flowers in shades of rose pink, purple, and occasionally white, with yellow-brown speckles on the upper petals. The flowers, measuring about 3.5 cm wide or more, have five lobes on the corolla, and the plant may even become a small tree up to 25 ft tall when crowded. The leaves, which are simple and alternate, are 7.5-15 cm long and 3-8 cm wide, tapering at both ends. The flower clusters are terminal and can contain 20 or more blooms. Overall, this species showcases the beauty of broadleaf evergreen shrubs and adds a touch of color to the Pacific Coast landscape.
