This Agastache differs from all other Agastache in the region, except for A. micrantha, by its small flowers. The calyx tube is less than 3 mm long. It has thicker leaves than A. micrantha, the leaves usually not wrinkling upon drying, the leaves mostly 1.5-2.0 (rather than 2.5-3.0) times longer than wide. Agastache micrantha is primarily of the Chihuahuan Desert region; A. wrightii occurs where the Sonoran influence is stronger.
