(Formosan Woodland Sage or Tai wan qin zhu cao) A native of Taiwan, this Salvia nipponica grows well in hot, humid climates as well as milder locales.
Blooming throughout fall, bright yellow flowers help this sage lighten a shady garden. Similar to other Woodland Sages, it can handle many sunlight conditions, including partial shade, full shade and a combination of morning sun and afternoon shade.
The sunny flowers contrast handsomely with the plant's arrowhead-shaped leaves that are deep green on top and hairy purple underneath. The foliage alone makes this a great planting choice for damp, shady spots. However, it needs somewhat warmer climes -- USDA Zones 7 to 9 -- than our other woodland sages.
Spreading gently, Formosana eventually clumps densely to become an effective groundcover. Grow this plant in rich, moist soil and give it plenty of water.
And if that's not enough, consider that this sage is an important anti-inflammatory herb in traditional Chinese herbal medicine. In the West, ongoing medical research is beginning to support this and show Formosana's role as an antioxidant as well.
(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.
Flowers by the Sea grows Salvias that are already popular in the Southeast as well as others we would like to introduce to gardeners seeking thirsty flowering plants that can also adjust to dry spells. Many are fine choices for Florida hummingbird gardens. Our suggestions are organized into categories based on moisture tolerance – average and ample -- as well as sun requirements.
Let there be light; let there be brightness. Yellows and oranges are cheerful colors to combine in a grouping of perennials. Pantone's spring 2013 designer colors -- golden yellow Lemon Zest 13-0756 and its hot orange Nectarine 16-1360 -- are fun colors to match to sages (Salvia spp.) that can turn up the light in a garden whether sunny or shady. Two groupings for sunny or shady gardens are offered
Sturdy, shade-loving Japanese Salvias are lovely additions to woodland gardens with their lush, large-leafed foliage and delicate-looking flowers in colors including pinks, purples and yellows. They're ideal for bordering shady paths where they invite visitors to pause for close-up views. Flowers by the Sea suggests Japanese species for woodland gardens and organizes them according to their cold hardiness.
This plant can handle extreme heat.
Full-sun Salvias that don’t like any shade are among the most heat tolerant. Heat-loving Salvias also are often drought tolerant. Moisture-conserving features, such as fuzzy leaves, help them stay perky at high temperatures.
Heat-tolerant Salvias are fine choices for western and southern exposures.
This plant thrives when planted where it will receive morning sun followed by afternoon shade, such as on the eastern side of a house. Make sure it isn’t exposed to midday and afternoon sun, which can damage tender leaves during the summer when sunlight is more intense due to being more direct.
Although midday is when sunlight is most direct, it takes time for the atmosphere to heat up and for heat to peak at sometime in the afternoon. Salvias that prefer cooler temperatures are protected by afternoon shade during the hottest time of year.
This plant grows well in partial shade, such as the kind on the edge of woodlands or under deciduous trees with breaks in the foliage through which dappled sunlight penetrates. Many Salvias thrive in partial shade, including ones that spend part of their day in full sunlight. Some species need partial shade to overcome severe heat and dry soil.
This plant grows well in an outdoor container, such as on a patio.
Some containerized Salvias leaf out and flower year after year following a period of dormancy. Annuals in containers may die back and appear to grow again when they reseed.
During extreme heat, check the soil in container plantings once or twice daily to be sure it doesn't completely dry out. Feel its surface for coolness, then gently poke a finger into the soil to check for dryness.
This herbaceous plant is known for its use in folk remedies.
Salvias have been used as healing herbs by a wide variety of cultures in the Americas, Europe and Asia. The genus name is from the Latin term “salvare,” which means to save.
When considering application of an herbal remedy to treat a medical problem, be sure to consult a physician first.
To create a harmonious landscape plan, it is important to consider the heights of individual plants.
Height also affects function. Short Salvias often make excellent ground covers that conserve soil moisture and discourage weeds while also brightening your yard. Medium-height Salvias, such as ones 36 inches tall, often are ideal border plants. A tall Salvia planted singly can highlight a landscape; multiple plantings can form an attractive screen.
Plant this herbaceous species in the USDA Zones where it grows as a perennial, returning year after year.
After dying back to the ground at frost, herbaceous perennials emerge in the Spring with soft, new growth. A Salvia that is perennial in one region, may be an annual in another depending on local conditions, such as winter temperatures.
If you live in USDA Zone 5, for example, Salvias in our catalog cited as growing well in Zone 5 or lower will be perennial. Those cited as doing well in Zones 6 or higher may do well in Zone 5, but generally will act like annuals coming back from seed instead of the parent plant’s roots.
By considering the width of a plant, you can determine how many to place in a row or what other plants to grow with it.
For example, a narrow, moderate-height Salvia may look good interplanted with bushier species, kind of like Mutt and Jeff.
In contrast, wide-spreading Salvias are economical for hiding lengths of wall and fence or for creating hedge-like divisions in a yard.
Plant hardiness Zones defined by the U.S. Department of Agriculture tell you the minimum temperatures a plant can withstand in your garden. The USDA divides the nation into winter climate areas from coldest (Zone 1) to warmest (Zone 11).
However, it is sometimes possible to grow a Zone 6 Salvia as a perennial in Zone 5 if you provide preferential care, such as winter mulching and a location sheltered from harsh winds. In contrast, a Zone 9 Salvia may act like a perennial in Zone 10 if given a bit of shade or extra water.
This plant thrives on or at least tolerates lots of water, especially when soil is well drained. They are generally not suitable for poorly drained soils.
A number of Salvias hold up well in areas where rainfall is a regular occurrence. Some even tolerate boggy conditions but only for a brief time. These are usually top-notch plants for regions of the country, such as the Southeast, where summers are soggy.
This plant reaches peak bloom in Fall or flowers for much of the season.
It may begin flowering much earlier in the year. Bloom time for some Salvias lasts from Spring till first frost. Others begin flowering in Summer and continue into Fall. There are also Salvias that don’t bloom until late Fall and continue into Winter if grown in mild-Winter areas.
There is a great deal of overlap in blooming seasons for Salvias.
