Ohio bloom calendar
Show the full bloom calendar (flowers with 15+ Ohio flowering records, earliest bloomers first)
Darker = more flowering sightings that month. Based on iNaturalist research-grade observations in Ohio 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 Ohio, 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 Ohio's official flowers and popular garden flowers that iNaturalist users record growing in Ohio. Every flower needs a CC0 or CC BY photo.
