Today I learned that I don’t know Snow on the Mountain (Euphorbia marginata) without the blooms. We’ve watched for it all summer and have been passing it without realizing. I’ll be paying more attention from now on. Today, they were there, in all their glory and made for a beautiful scene with the dew, the fog and the pasture!
Snow on the Mountain is native in most of the lower 48 states including Oklahoma. It grows 1-3′ high and is an annual.
This plant is toxic if consumed but can cause severe allergic reactions in some individuals just from being handled.
Probably the most interesting thing about this plant are the flowers. The actual flowers are pretty small and inconspicuous. The parts we see and think are flowers are actually modified leaves called bracts surrounding the small flowers, much like it’s relative the Poinsettia.
Snow on the Mountain can be confused with Snow on the Prairie. Snow on the Prairie Euphorbia bicolor is only native to the southern United States. See if you can tell the difference:
Below are images that show the plant to help with future identification. Not as scenic but helpful. These were taken later the same day after it warmed up, in the same location.
