Salvia nemorosa is an herbaceous perennial with a clump forming habit. Its mid green leaves are narrowly oval and rough. In summer until autumn it will bear branching racemes, densely set with whorls of violet-blue flowers.

S. nemorosa, commonly known as woodland sage, is native to much of central Europe and western Asia. Sage was traditionally used by herbalists to treat maladies of the head; John Gerard noted in The Healing Herbs that is was ‘singularly good for the head and brain. It quickeneth the senses and memory, strengthens the sinews, restores health to those that have palsy, and taketh away shaky trembling of the members’.

Salvia is derived from the Latin ‘salvare’, meaning to ‘save’ or ‘heal’, in reference to its historical use as a medicinal plant. Nemorosa is also Latin meaning ‘shady’, in reference to its woodland origins.
