Euphorbia marginata (commonly known as snow-on-the-mountain, smoke-on-the-prairie, variegated spurge, or whitemargined spurge) is a small annual in the spurge family.
It is native to parts of temperate North America, from Eastern Canada to the Southwestern United States. [2] It is naturalized throughout much of China. [3]
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. [4] [5]
Description
Snow-on-the-mountain has grey-green leaves along branches and smaller leaves ( bracts or cyathophylls) 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.
Snow-on-the-mountain has also been found to emit large quantities of sulfur gas, mainly in the form of dimethyl sulfide (DMS). [6]
