Whether you call it a shrub or a tree, Salvia arborescens rises up to an impressive 12 feet tall and 5 feet wide. Commonly known as Sage Tree, this Salvia grows well in full sun, but prefers partial shade.
It is the size of this plant more than its floral display that is its main attraction. Cream to yellow and tiny, each flower has long, graceful anthers that extend far beyond its corolla. The foliage is bright green to forest green with lance-shaped leaves.
Sage Tree works well as a screen or background planting In rich, well-drained soil. It also looks handsome in shrubby borders and is a good solution for moist areas of the yard. You can even grow it in a large container, but expect it to rise to a shorter height than it would in the ground. Deer mostly avoid Salvias, so this is one tree they likely won't nibble on.
Swedish botanist Erik Ekman collected Salvia arborscens during the 1920s in the Caribbean. Commonly known as Sage Tree, it was one of more than 2,000 species that he introduced to science during his 14 years of research in Cuba, Haiti and the Dominican Republic.
The Dominican Republic's Partners for Rural Health organization notes that the leaves are used as a folk remedy for diarrhea. However, it warns that they may be dangerously narcotic. So don't cook with this sage.
(Forest Fire Tropical Sage) Butterflies love the abundant, fire engine red flowers of this mostly annual sage. It's a popular cultivar of one of the first Salvias used for ornamental purposes -- Tropical Sage. The flowers are dramatically framed by reddish black bracts.
(Door of the Fox Mexican Sage) Purplish foliage contrasts attractively with the violet-to-purple flowers of this big sage, which grows 6 feet tall and 4 feet wide. Bloom time is autumn. This darkly dramatic Mexican Sage makes a particularly attractive entryway accent.
(Tall Red Colombian Sage) Salvia rubescens subsp. dolichothrix may tower over your head when in full bloom with its creamy red trumpet blossoms and dark calyxes. Its leaves are large and attractively textured.
(Plum Wine Autumn Sage) Frilly, lavender-tinged, pink flowers with a pretty white dot at the throat make this another outstanding contribution from North Carolina nurseryman Richard Dufresne.
(Orchid Glow Sage) Sages can be such tough plants withstanding heat and drought. Yet so many, including Salvia 'Orchid Glow' have delicate looking blossoms. This one has large, bright magenta flowers with white beelines.

Synopsis:
Moon gardens contain plants with pale flowers -- especially whites -- and silvery or variegated foliage that shine in moonlight. Some gardeners plant them to glow from afar when peering into the dark through a window. Others design these gardens for nighttime rambles. A number of white-flowered sages would be excellent additions to the dreamy design of a moon garden.

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 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 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 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.
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.
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 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.

Lots of Summer bloomers start flowering in Spring; others begin in Summer and keep up the show of color until frost.

Wildlife
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.
