Darker = more flowering sightings that month. Based on iNaturalist research-grade observations in Oklahoma 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 Oklahoma, 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 Oklahoma's official flowers and popular garden flowers that iNaturalist users record growing in Oklahoma. Every flower needs a CC0 or CC BY photo.
Rare plant list: Oklahoma has no state law listing endangered or threatened plants, so we show NatureServe's Oklahoma ranks instead.
