This Solidago is widespread from Alaska down the Rockies to Mexico to Virginia to Quebec.  It grows from an inch tall in tundra to a foot-and-a-half tall in more hospitable environments.  It is usually shorter than S. multiradiata and has about eight rays per flower head whereas S. multiradiata has about thirteen.  Both have small, clustered, very bright golden yellow flowers giving plants a very soft, fuzzy appearance.

"Simplex" is Latin for "simple".  The plant was first collected for science near Santa Rosa, Mexico in 1820 by Humboldt.
