What Is the Washington State’s Flower?
If you’ve ever wondered, “What is the state flower of Washington?” you’re in for a treat. The Washington state flower is the Coast Rhododendron (Rhododendron macrophyllum), a breathtaking evergreen shrub that bursts into vibrant pink blooms every spring. Officially named the state flower of Washington state in 1959, it’s a symbol of the Pacific Northwest’s natural beauty. I first encountered this plant on a hiking trip in Washington years ago, and its clusters of bell-shaped flowers instantly stole my heart.
In this article, I’ll walk you through its fascinating history, botanical details, growing tips, and even some fun facts—everything you need to appreciate and cultivate this gem. Whether you’re a seasoned gardener or just starting out, there’s something here for everyone.
A Brief History of the State Flower of Washington
The journey of the Coast Rhododendron to becoming the state flower Washington is a fun tale. Back in 1892, before Washington women had the right to vote, a group of ladies chose the rhododendron as a floral emblem for the state’s exhibit at the Chicago World’s Fair. They loved its beauty and resilience—qualities that mirrored the spirit of Washingtonians.
Fast forward to 1959, when the Washington State Legislature officially declared the Coast Rhododendron the state flower of Washington state. Why this species? It’s native to the region, thriving in the wild from British Columbia down to Northern California. For me, knowing this history makes every bloom I see feel like a little piece of Washington’s past.

Botanical Description: What Makes the Coast Rhododendron Special?
Let’s get up close and personal with the Washington state flower. The Coast Rhododendron is an evergreen shrub that can grow 6 to 15 feet tall in the wild, though in gardens, it’s often more compact—perfect for landscaping! Its leaves are dark green, leathery, and oblong, providing year-round interest even when it’s not blooming.
Come late spring to early summer, it explodes with clusters of pink flowers (sometimes white or pale purple in rare varieties). Each bloom is about 2-3 inches wide, with a delicate, bell-like shape that attracts bees and butterflies. I’ve spent many mornings sipping coffee and watching pollinators dance around my own rhododendrons—it’s pure magic.

Growing Conditions: How to Bring the Washington State Flower Home
Dreaming of adding the state flower of Washington to your garden? Good news—it’s totally doable with the right setup. Here’s what I’ve learned from growing these beauties at home:
Soil
- Coast Rhododendrons love acidic, well-drained soil with a pH of 4.5 to 6.0. I mix in some pine needles or peat moss to keep things just right.
Sunlight
- They thrive in partial shade—think dappled sunlight under trees. Too much direct sun can scorch the leaves, while too little can reduce blooms. My backyard has a spot under an oak tree that’s perfect.
Climate
- These plants adore Washington’s mild, wet winters and cool summers (USDA Zones 7-9). If you’re outside this range, container gardening might be your best bet.
Water
- Keep the soil consistently moist but not soggy. I water mine deeply once a week during dry spells.

Care Tips: Keeping Your Coast Rhododendron Thriving
Once you’ve planted your Washington state flower, a little TLC goes a long way. Here’s my go-to care routine:
Planting
- Dig a hole twice as wide as the root ball but no deeper. I learned the hard way that planting too deep can stress the roots.
Watering
- Water regularly the first year to establish roots. After that, they’re fairly drought-tolerant—handy for busy gardeners like me!
Pruning
- Trim dead or crossing branches after flowering to maintain shape. I snip mine in June, and they bounce back beautifully.
Pest Control
- Watch for pests like aphids or root weevils. A blast of water or some neem oil usually does the trick in my garden.
Fertilizing
- Use an acid-loving plant fertilizer in spring. I swear by a slow-release option—it’s low fuss and keeps my rhodies happy.
