(Makino) We would grow this rare clone of the woodland Japanese native Salvia glabrescens even if it never flowered, because the arrow-shaped foliage is so lush, toothed and colorful. As they age, the arrow-shaped leaves transform from yellowish green to dark green.

(Japanese Woodland Sage or Shu Wei Cao) This short, lavender-flowered, ornamental sage has purple-to-green foliage. In Asia, this woodland plant has long been an important medicinal herb, used in the treatment of conditions such as diabetes.

(Shinano-akigiri) Japan's largest island, Honshu, is home to Salvia koyamae, a shade- and moisture-loving herbaceous perennial that is perfect for woodland gardens or shady borders. It is notable for yellow flowers, which bloom from late summer into fall, as well as arrow-shaped foliage.

(Kyushu Woodland Sage) We are in love with this short forest sage from Kyushu, Japan. Its clusters of large creamy flowers pale as fresh-churned butter begin blooming in September. Even when not blooming, its foliage is showy in a shady garden.
