Hawaii bloom calendar

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