What is the state flower of Washington?
The coast rhododendron (Rhododendron macrophyllum) holds a special place in the hearts of Washingtonians as the official state flower. Known for its vibrant pink blooms and its ability to thrive in the state’s temperate climate, this native shrub reflects the beauty of Washington’s natural landscapes. Let’s dive into the history, significance, and care of the coast rhododendron, the state flower of Washington.
History of the Washington State Flower
Scottish naturalist Archibald Menzies first documented the coast rhododendron during Captain George Vancouver exploration of the Pacific Northwest in the late 18th century.
The coast rhododendron’s journey to becoming Washington’s state flower began in the late 19th century. In 1892, women across the state were asked to vote for a flower to represent Washington at the Chicago World’s Fair in 1893. Out of several contenders, including the clover and the dogwood, the coast rhododendron emerged victorious thanks to its striking beauty and abundance in the state’s forests. The flower is also known as the Pacific rhododendron.
However, it wasn’t until 1959 that the coast rhododendron was officially adopted as the Washington state flower by the state legislature. The choice was a testament to the plant’s iconic status and its role in showcasing the natural splendor of the Evergreen State.
Washington’s love affair with the coast rhododendron stems from its vibrant blooms, which can be seen along the state’s coastal areas and forested regions during late spring and early summer. The plant’s hardy nature and stunning blossoms made it a fitting representation of the state’s rugged beauty.

Growing and Caring for Coast Rhododendrons
If you’re inspired to add a touch of Washington’s state flower to your garden, here’s how to grow and care for coast rhododendrons at home:
Soil
These plants thrive in well-drained, acidic soil rich in organic matter. Mulching with pine needles or bark can help maintain soil acidity.
Sunlight
Coast rhododendrons prefer partial shade but can tolerate full sun in cooler climates. Too much direct sunlight can scorch the leaves.
Watering
These shrubs prefer consistently moist but well-drained soil, as soggy conditions can lead to root rot. During dry spells, especially in summer, they require deep watering to keep the roots hydrated, as their shallow root systems can dry out quickly. It’s best to water early in the morning to allow the foliage to dry by evening, reducing the risk of fungal diseases. Mulching around the base with organic materials like bark or pine needles can help retain soil moisture and protect the roots.
Zones
The coast rhododendron is best suited for USDA zones 7-9, which align with the Pacific Northwest’s climate.
Pruning
Pruning coast rhododendrons is an important step to maintain their shape, encourage healthy growth, and enhance their blooms. The best time to prune is right after the flowering period in late spring or early summer, as this allows the plant to set buds for the next season. Start by removing any dead, damaged, or diseased branches to improve the plant’s overall health. Next, trim back overgrown or leggy branches to shape the shrub and promote a more compact form. If necessary, rejuvenation pruning can be done by cutting back older stems to the base, which stimulates fresh growth from the roots.
