Meaning of the Scientific and Common Names

Scientific Name

The genus name, Solidago, derives from the Latin words, Solidus and ago, which together mean to make (ago) whole (Solidus). This meaning comes from the medicinal uses of the plant. The species name, caesia, is a Latin word for bluish-grey, presumably for the color of the stems.

Common Name and Alternative Names

The common name comes from the wreathed appearance of the flowers on the stem (Glattstein 1991). Other common names include blue-stem goldenrod, axillary goldenrod, bluish goldenrod (Latham and Rhoads 2006), and woodland goldenrod. In Canada it can be called Verge d’or bleuatre (Gillett 1991).
