(Stem Clasping Violet Sage) Like a candelabra lit up with whorls of violet blossoms, the erect, branching flower spikes of Salvia amplexicaulis make this native of Southeastern Europe shine. On the Grecian island of Thassos, it brightens areas near the beach.
The summer-blooming flowers are nestled inside leaf-like burgundy bracts that attach directly to, or clasp, the flower stems without petioles. This gives the plant its common name. Its bright green, fragrant foliage has attractively bumpy, lance-shaped leaves. This sage is a good choice for perennial borders, woodland gardens and cut-flower beds.
Although S. amplexicaulis does fine with regular watering, it does love moisture. So it is an ideal choice for moist problem areas in the yard. Give it a setting with full sun to partial shade along with average garden soil that drains well. Deadhead the flowers to prolong bloom time and keep butterflies visiting. Speaking of wildlife, deer tend to avoid most sages including this one.
Here’s another reason to love this pretty plant: Scientists think that the essential oil of S. amplexicaulis may be useful in fighting bacterial infections.

Synopsis:
Dry gardens are flowerbeds or entire landscapes based on ornamental perennials that require little to no watering once well rooted. Many Salvias are excellent, drought-resistant choices for these gardens. Flowers by the Sea Farm and Online Nursery talks about dry garden myths as well as low-water plants.

Synopsis:
Randy Collins was surprised when he got hooked on horticulture following retirement. But after a move to South Carolina, he was even more surprised at how deer destroyed his gardens until he began growing lots of mint family (Lamiaceae) plants like Salvias. It inspired him to write Stop...and Smell the Mints.

Quick Digs is a serial containing short posts focused on a central issue about Salvia gardening. The topic for the first series is Salvia groundcovers for weed control, and this is the third article.
If you are a Salvia lover facing the difficult scenario of cold winters and damp soil, the sages listed here are right for winter conditions from USDA Zone 5 to 9. All are water-loving, shade-tolerant species and have handsome foliage that adds to landscaping even when the plants aren't blooming. By massing these plants, you gain coverage more rapidly and increase weed deterrence.

Synopsis:
High altitude, distance from large bodies of water and powerful chinook winds make the Rocky Mountain West a dry gardening environment even in years of higher than average rain and snow. The region's steep mountains have a major impact on where and how precipitation falls. Instead of a single mountain chain, the Rocky Mountains are made up of 100 separate ranges. Similarly, the Salvia genus contains a broad range of sages, many of which thrive in the climactic extremes of the Mountain West.

Learn more about how we analyze plant colors
We based our analysis of this plant’s floral and foliar color on the internationally standardized color system published by the U.K.’s Royal Horticultural Society. Called the RHS Large Colour Charts, this publication is a boxed set of color swatches arranged in fans and containing all the colors that RHS has identified in horticulture. RHS gives each color a common name and code number.
Each swatch has a small hole punched into it. We place the swatch over a flower petal and compare the blossom’s color to that of the card. When using RHS colors to compare plants that you want to combine in a flowerbed, in bouquets or in some other manner, RHS says to view them indoors in north light. If you are matching our digital swatches to flowers already in your garden, pluck two or three fully open blossoms of each plant that requires analysis.
You may find that the plant you receive from FBTS varies somewhat in color from what appears in our color analysis or our photograph due to a number of factors, including:
- Variations in photographic colors based on lighting level at different times of day
- Differences in the resolution of digital screens
- Seasonal changes in plant color due to changes in temperature and plant cycle and
- pH or soil chemistry that varies from one locale to another and causes color shifts.
Finally, RHS notes that you shouldn’t attempt color matching when your eyes are fatigued.
Here are some guidelines for success with this plant in your garden.

Exposure
This plant needs or tolerates more than six hours of intense sunlight daily. Many Salvias only thrive in wide-open locations where they receive long hours of full sun. However, full-sun species sometimes tolerate a bit of partial shade. Or a Salvia that loves partial shade may be amenable to spending part of its time in full sun.
In general, this sun/shade adaptability shows up in Salvias that do best in cooler climates when grown in full sun and thrive in hot climates when partial shade is available. So full-sun Salvias sometimes are also categorized as partial-shade plants and vice versa.
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
Growing Habit
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.
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.
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 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.
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
Wildlife
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.
Unless local forage is in short supply, most deer likely will avoid this plant.
It appears that deer dislike Salvias, in general, due to their volatile oils that make the plants so fragrant and savory in cooking. However, the only completely deer-proof plants are the ones grown beyond reach.
