Washington bloom calendar
Show the full bloom calendar (flowers with 15+ Washington flowering records, earliest bloomers first)
Darker = more flowering sightings that month. Based on iNaturalist research-grade observations in Washington marked “Flowering,” as of October 17, 2026. Garden flowers have few records because research-grade data leaves out planted ones.
How we picked these flowers
We started from iNaturalist's research-grade sightings in Washington, most-observed first, left out grasses, sedges, trees and other plants with tiny or wind-pollinated flowers (plus poison ivy), kept at most three species per genus, and added Washington's official flowers and popular garden flowers that iNaturalist users record growing in Washington. Every flower needs a CC0 or CC BY photo.
Rare plant list: Washington has no state law listing endangered or threatened plants (the Washington Natural Heritage Program's rare plant list isn't regulatory), so we show NatureServe's Washington ranks instead.
Invasive plant list: Washington State noxious weed list (WAC 16-750-005, -011, -015)
