This description is for Salvia nemorosa: A striking addition to any garden, Salvia nemorosa is a woody perennial with a central stalk that is laced heavily with purple blossoms, and with enough clumped together, a sleepy purple haze is created. Depending on the variety, the flowers can be violet, purple, white or pink, so the spectacle can become even more remarkable. Known as the Woodland Sage, it is one of the hardiest of its type, surviving even harsh winters. It has dull green foliage and is adaptable to most soil types but prefers moist yet well-drained areas. It’s excellent for beautifying barren slopes, rockeries and gravel beds.
