(Bitter Mexican Sage) Hummingbirds love this heat-tolerant Salvia, which is one of our best choices for shady, moist areas. The large-lipped, baby-blue flowers with white striations bloom from late summer through fall.
This compact shrub grows well in the garden or in a container, especially where it will receive morning sun and afternoon shade or partial shade all day. In its native Mexico, it is used as a folk remedy for a variety of ailments. We love its grace and beauty in the garden!
(Recurved Sage) At home in the shady, high-altitude cloud forests of Southern Mexico and Guatemala, this large, lush sage requires a warm, moist climate. In cool climates, it can handle full sun. However, partial shade is a better choice in most gardens.
(Kellerman's Sage) Rare in the United States, this wooly leafed, upright shrub comes from Southern Mexico and Guatemala. Mid-size, powder-blue flowers bloom on its long, airy stems from summer through winter in mild climates. It's lovely in mixed, drought-resistant plantings.
(Wooly Multicolor Sage) In Greek, "lasiantha" means "wooly flower." The flowers of Salvia lasiantha are surrounded by wooly bracts, but are even more notable for transforming from apricot-orange in the morning to reddish-purple later in the day.
(Rosy Bract Sage) Sub-shrub salvias have both woody and soft, herbaceous growth. Rosy Bract Sage is a tidy, small leafed sub-shrub smothered with large clusters of 1/2-inch, violet-blue flowers and rosy red bracts. Its bracts deepen in color as the season proceeds.

The FBTS Sage Experts series focuses on Salvia specialists -- both amateurs and professionals -- in settings ranging from botanic gardens to universities. This article focuses on Jesús Guadalupe González-Gallegos of the University of Guadalajara, an expert in the taxonomy of Salvias native to Western Mexico. He discusses the megadiversity of Mexican flora and problems involving incorrect identification of sage species.

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.

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.
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.
Shrubs are characterized not only by bushy foliage but also by woody stems.
Shrubby Salvias may be evergreen or deciduous. Some Winter-blooming, deciduous species lose their foliage during hot weather. Some Salvias, classified as subshrubs, have a combination of woody and tender, herbaceous growth.
Salvia shrubs range from tall, upright species to ground covers of short to moderate height. Their spread may match or exceed their height
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.
A number of Salvias hold up well in areas where rainfall is a regular occurrence. Some even tolerate boggy conditions. 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.
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.
Based on our experience and reports from customers, hummingbirds (Trochilidae spp.) love this plant.
Hummingbirds exist only in the Americas where their 300-plus species are particularly fond of the nectar in brightly colored Salvias from the Western Hemisphere. However, if favorites aren’t available, they dine on the nectar of most Salvias.
Hummingbirds repay thoughtful plantings by helping to pollinate your garden
