When the wildflowers peak

Bluebonnets in the Hill Country, poppies at Antelope Valley, lupine above Crested Butte — every big bloom has a rhythm, and spring climbs the map like a ladder: desert floor first, alpine meadows last. Here's where the year stands.

Is this a superbloom year?

The desert superblooms — Death Valley, Anza-Borrego, the Carrizo Plain — follow the winter rain, and the rain is measurable months before the first flower opens. We track it storm by storm.

How we call the windows

Based on reports from iNaturalist naturalists. Thousands of dated, expert-checked flowering reports trace each bloom's usual rhythm — when it starts, when it peaks, when it fades — and this year's reports show whether the season is running early or late.

We name public reserves, parks, and roads only — never exact pins, never private land.
