Indiana in bloom

Indiana bloom calendar

Darker = more flowering sightings that month. Based on iNaturalist research-grade observations in Indiana 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 Indiana, 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 Indiana's official flowers, plus flowering shrubs and trees with at least 3 garden or 10 wild iNaturalist records in Indiana and popular garden flowers that iNaturalist users record growing in Indiana. Every flower needs a CC0 or CC BY photo.

Rare plant list: Indiana has no state law listing endangered or threatened plants (the DNR keeps a rare plant list, but it isn't regulatory), so we show NatureServe's Indiana ranks instead.
Invasive plant list: Indiana prohibited invasive terrestrial plants (312 IAC 18-3-25)
