Montana bloom calendar
Show the full bloom calendar (flowers with 15+ Montana flowering records, earliest bloomers first)
Darker = more flowering sightings that month. Based on iNaturalist research-grade observations in Montana 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 Montana, 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 Montana's official flowers and popular garden flowers that iNaturalist users record growing in Montana. Every flower needs a CC0 or CC BY photo.
Rare plant list: Montana has no state law listing endangered or threatened plants, so we show NatureServe's Montana ranks instead.
