Wildflowers of Arizona

When winter rains cooperate, the Sonoran Desert erupts in gold, orange, and magenta — one of the great wildflower shows of the Southwest.

Overview

Arizona's wildflower season starts low and early, with desert annuals blooming from February into April, then climbs into the mountains through summer. In years with well-timed winter rain, the desert floor around Phoenix, Tucson, and the Superstition Mountains fills with color.

This guide covers common and iconic Arizona wildflowers — how to recognize them and when they bloom. Photograph the flower and leaves and use the app to confirm any bloom you find.
