Made for Shade: Japanese Woodland Salvias
Sturdy, shade-loving Japanese Salvias are lovely additions to woodland gardens with their deceptively delicate-looking flowers and lush, large-leafed foliage. They are ideal for bordering curving pathways through trees and other woodland plants, because they invite visitors to pause for close-up views.
If you've ever visited a Japanese garden, you probably have noticed a number of key elements contributing to the serene atmosphere, including:
Backyard Woodland Refuges
Of course, woodland gardens needn't be so elaborate. You can transform a portion of your yard containing trees and bushes into a more pleasing setting with the addition of artfully arranged stepping stones and flowering perennials.
Enchanting woodland gardens, whether Japanese or any style, are partial and to full shade settings. They may even include hidden clearings such as the "secret" outdoor dining area that garden writer Kevin Lee Jacobs created in his woodland garden, where he used wood chips for flooring. To surprise his dinner guests, Jacobs sets a formal table -- complete with china, cloth napkins and flatware -- behind a screen of trees and shrubs, including honeysuckle.
A birdbath with a mister to attract hovering hummingbirds can be placed in a partially shaded spot to invoke the soothing sounds and appearance of water.
Partial shade is best for birdbaths, because full sunlight encourages algal growth and makes water too warm for birds. Conversely, full-shade areas aren't good locations due to offering cover for predators such as cats.
Evelyn J. Haddon of the Less Lawn website suggests creating a dry stream of gravel or rocks running through the garden if you don't have the money or time for a real water feature. Adding some large rocks and boulders increases the riparian look.
Eight Shady Japanese Sages
Japan's woodlands are home to lovely, cold-hardy sages, many of which also tolerate heat. These are water-loving plants that can handle damp areas in the yard, but also do well in drier areas with average watering.
Aside from lining paths, these sages are excellent in containers and as groundcovers. Plant them in rich, well-drained soil.
Here are eight to enjoy in your gardens. We've organized them by USDA Plant Hardiness Zones and have indicated the minimum temperatures they tolerate.
Zone 4 (-30 Degrees F)
Shinano-akigiri (Salvia koyamae) Zones 4 to 9
Yellow shade Salvias are rare; this is our best one. It is so cold resistant and popular that we grow it year round. At times when it is out of stock, all you have to do is click on the email me when back in stock button for immediate notice when it is available again.
Zone 5 (-20 Degrees F)
Japanese Woodland Sage or Shu Wei Cao (Salvia japonica)
This long-blooming sage has edible foliage.
Pink Makino (Salvia glabrescens 'Momobana') Zones 5 to 9
The bottom lip of this sage looks like a tutu in contrast to the tall, slender, upper lip, which might be imagined as a ballerina's torso. By the way, roughly translated, momobana means "pink flower."
Makino (Salvia glabrascens 'Shi Ho') Zones 5 to 9
The toothed foliage of this Makino transforms from bright to dark green as the season unfolds.
Makino (Salvia glabrascens 'Yellow & Purple') Zones 5 to 9
This is a slow-growing plant, but well worth the wait for its translucent flowers with dramatic beelines. The common name of all three S. glabrescens species likely honors Tomitaro Makino (1862-1957), who is often called the father of Japanese botany.
Zone 6 (-10 Degrees F)
Kyushu Woodland Sage (Salvia nipponica 'BSWJ5829') Zones 6 to 9
This plant's unusual cultivar name is its collection number, which is assigned when you scientifically name a plant.
Variegated Japanese Woodland Sage (Salvia nipponica 'Fuji Snow') Zones 6 to 9
Irregular white mottling and edges give this sage a bright look in the shade.
Zone 7 (0 degrees F)
Formosan Woodland Sage or Tai wan qin zhu cao (Salvia nipponica var. formosana) Zones 7 to 9
As part of our Special Orders Program, this sage is not regularly in stock. Instead, we grow it for you when we receive your order. This takes about six weeks.

Salvia koyamae Returns to FBTS
Salvia koyamae is back and waiting for you at Flowers by the Sea. Plant this shade-loving groundcover now for strong root growth. It will reward you with large, arrow-shaped leaves and buttery yellow flowers that bloom in autumn.
Sometimes through no intention of our own, a beautiful plant we love remains out of production far longer than intended. Any number of problems may occur to cause such a disappearance.
We're happy that S. koyamae -- one of our best woodland sages for damp, shady conditions -- is available again. Sometimes referred to simply as Yellow Sage, it is also commonly known as Shinano-akigiri.
Koyama Spruce is a rare plant that is endemic to Japan's island of Honshu. S. koyamae is also a Honshu native along with its close relatives S. glabrescens (known commonly as Makino ) and S. nipponica. The Salvias by Origin category in our product menu (the thick green bar at the top of the page) contains links to lists of sages from many regions of the world, including one titled Japanese Natives.
Tomitaro Makino (1862-1957), who is often called the father of Japanese botany, gave S. koyamae its scientific name in 1922. He most likely named it for Japanese botanist Mitsuo Koyama (1885-1935) for whom Koyama Spruce (Picea koyamae) is named.
Makino was born during a period of great upheaval and modernization in Japan. He discovered botany during early childhood, a period of personal upheaval when he had to drop out of school for a number of years following the death of his parents.
In time, Makino became a famous modernizer in the plant world despite beginning his career as a self-taught botanist and plant explorer. He was one of the first Japanese botanists to classify plants using the Linnean system of binomial nomenclature in which each plant is given a two-part name -- genus and species -- possessed by no other plant in the world.
Shinano-akigiri is one of the thousands of Japanese flora that Makino classified. It brightens partial to full shade and survives heat, cold and humidity . We're glad that Makino brought this woodland beauty to the attention of the horticultural world.
