This map is based on our research. We have checked its accuracy to Level 3 ecoregions. Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

This species is native to the central US, south well into Mexico, and north barely into Canada. It has however expanded westward in the US and Canada. Because this genus is hard to ID, and has already been found in a wide variety of habitats and ecoregions, it is likely more widespread than reported.
