Darker = more flowering sightings that month. Based on iNaturalist research-grade observations in Wyoming 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 Wyoming, 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 Wyoming's official flowers and popular garden flowers that iNaturalist users record growing in Wyoming. Every flower needs a CC0 or CC BY photo.

Rare plant list: Wyoming has no state law listing endangered or threatened plants, so we show NatureServe's Wyoming ranks instead.
Invasive plant list: Wyoming state designated noxious weeds (W.S. 11-5-102(a)(xi)), as listed by the Wyoming Weed & Pest Council
