(Giant Dan-shen) This strain is highly vigorous and grows larger than others of this species. The flowers are larger as well, and the inflorescence are taller and longer lasting. We are happy to offer this variety for the first time in 2019.
The bright red, finger-like roots of Salvia miltiorrhiza have a long history in traditional Chinese herbal medicine. WebMD reports that Danshen is used in Asia to treat a number of cardiovascular problems and "appears to thin the blood by preventing platelet and blood clotting." It is the subject of ongoing medical research.
Danshen has fragrant violet-blue flowers that bloom in summer and seem to glow in the shade. This woodland plant grows well in partial shade, prefers rich, well-drained soil and can handle ample moisture. Native to Asia, including areas that experience winter chill, it grows well in USDA Zones 6 to 9.
Here are some guidelines for success with this plant in your garden.

Exposure
This plant tolerates deep shade almost all day, such as under dense trees or on the north side of a building. Few Salvias can do this; those that do are highly valued. 
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.
Garden Uses
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.
Growing Habit
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.
Water Needs
This plant needs regular watering based on what is appropriate to your local conditions.
In some extremely hot, arid climates, this may mean daily watering in Summer. Although many drought-resistant Salvias survive on little to no watering due to local rainfall and deep roots meeting their moisture needs, others need regular doses. The size and frequency of the dose depends on your climate.
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.
Blooming Season
This plant reaches peak bloom in Summer or flowers for much of the season.
Lots of Summer bloomers start flowering in Spring; others begin in Summer and keep up the show of color until frost.
There is a great deal of overlap in blooming seasons for Salvias.
Wildlife
Honeybees love this plant’s nectar. As a honeybee burrows down into a Salvia’s nectar-rich flowers to reach dinner, it accidentally gathers pollen and drops it on the stigma of that blossom or of ones on other nearby Salvias. Fertilization results in seed production.
By growing honeybee favorites, you attract these helpful pollinators to all your flowering plants and increase productivity
This plant attracts butterflies whether for nectar or as a host for their caterpillars. Some butterflies feed on a limited range of flowering plants and only lay eggs on one kind of host plant. Salvia nectar lures adult butterflies. Placing host plants, such as Milkweeds (Asclepias spp.), next to nectar plants builds butterfly habitat. In exchange, the butterflies improve fertility in your garden through pollination.
(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.
(Yunnan Sage or yun nan shu wei cao) Yunnan Sage's tall spikes of violet-to-purple flowers bloom from summer into fall. Native to Southwestern China's provinces of Yunnan, Guizhou and Sichuan, it grows on shady, grassy hillsides and along forest margins at elevations up to 9,500 feet.
