Utah in bloom

Utah bloom calendar

Darker = more flowering sightings that month. Based on iNaturalist research-grade observations in Utah marked “Flowering,” as of October 17–23, 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 Utah, 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 Utah's official flowers, plus flowering shrubs and trees with at least 3 garden or 10 wild iNaturalist records in Utah and popular garden flowers that iNaturalist users record growing in Utah. Every flower needs a CC0 or CC BY photo.

Rare plant list: Utah has no state law listing endangered or threatened plants, so we show NatureServe's Utah ranks instead.
