(Shinano-akigiri) Japan's largest island, Honshu, is home to Salvia koyamae, a shade- and moisture-loving herbaceous perennial. It is notable for arrow-shaped foliage and translucent, yellow flowers blooming from late summer into fall.

Large and lush, the yellow-green hairy leaves of this sage form loose, gently spreading clumps. Although it can tolerate some morning sun, this is a shade-loving sage. It is a hardy choice for shady groundcovers, borders, containers, woodland settings and moist areas.

An underused gem of a plant, Salvia koyamae and presents the added bonus of being disagreeable to deer. Highly recommended.
