Herbaceous perennial sage from China commonly found in the Gansu Province as well as Yunan. This is a beautiful sage with the same medicinal attributes as regular Dan Shen or Red Sage. Gansu Red Sage also has bright, reddish colored roots and blooms to 2 feet with very attractive, bluish purple flowers in spring. Gansu Dan Shen inhibits vascular constriction making it an important herb in preventing stroke and is useful for all issues affecting the circulatory system. As a lover of salvias, this one is really stunning both as a rosette and in bloom. Prefers full sun. Perennial. Hardy to Zone 4.
