Wikipedia Article About Sage on Wikipedia
Common sage (Salvia officinalis) is a small evergreen subshrub, with woody stems, grayish leaves, and blue to purplish flowers native to southern Europe and the Mediterranean region.
It is much cultivated as a kitchen and medicinal herb, and is also called Garden sage, Kitchen sage, and Dalmatian sage. In southern Europe related species are sometimes cultivated for the same purpose, and may be confused with the common sage. Although this plant was the one originally called by this name sage, a number of related species are now also called by it, and are described in more detail in the article on sage.
