Euphorbia marginata, snow-on-the-mountain, smoke-on-the-prairie, variegated spurge, whitemargined spurge, is a small shrub in the Euphorbiaceae or spurge family native to parts of temperate North America.[1] It is found from Eastern Canada to California. [1]

The type specimen was collected in Rosebud County, Montana from the area of the Yellowstone River by William Clark during the Lewis and Clark Expedition.[2][3]


Euphorbia marginata plant has grey-green leaves along branches and smaller leaves in terminal whorls with edges trimmed with wide white bands, creating, together with the white flowers, the appearance that gives the plant its common names.
