Darker = more flowering sightings that month. Based on iNaturalist research-grade observations in Massachusetts 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 Massachusetts, 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 Massachusetts's official flowers and popular garden flowers that iNaturalist users record growing in Massachusetts. Every flower needs a CC0 or CC BY photo.
