Alaska in bloom

Alaska bloom calendar

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

Rare plant list: Alaska has no state law listing endangered or threatened plants, so we show NatureServe's Alaska ranks instead.
Invasive plant list: Alaska prohibited and restricted noxious weeds (11 AAC 34.020)
