Euphorbia marginata, or Snow on the Mountain, is native to the central US, and is adventive in the entire eastern US, as well as parts of the southwest. It grows in prairies, along railroads and roadsides, in pastures, fields and waste areas.

There are many, many species of Euphorbia in the US, most of them native. However, the closest to this species is Euphorbia bicolor, which looks very similar and has an overlapping distribution in part. The two can be distinguished by their leaves - Euphorbia bicolor has narrower, longer leaves, while Euphorbia marginata has shorter, more oval-shaped leaves.
