(Radio Red Autumn Sage) Dark calyxes support true red blossoms in Salvia greggii 'Radio Red', a 2015 introduction from the Darwin Perennials division of Ball Seed. Its tiny, smooth, elliptical leaves form a light, airy backdrop for the dramatic flowers.
Well branched, short, compact and long blooming, Radio Red Autumn Sage is an excellent choice for containers or front of border. Although adaptable to many kinds of gardens, this cultivar prefers average watering based on local rainfall.
Radio Red grows well in full sun, but can handle partial shade for part of the day. Deer avoid it, but honeybees and hummingbirds enjoy the nectar and pollen of this vigorous, cold-tolerant perennial.
Western pioneer and plant explorer Josiah Gregg introduced Autumn Sage to horticulture in 1846. He collected it in the Southwest while working as a scout and Spanish interpreter for the U.S. Army during the Mexican-American War.
Although first cultivated in 1885 and a long-time staple in Texas gardens, Salvia greggii didn't show up in plant nurseries until about 100 years later. Now it is one of the most popular species of Salvia for home gardens.

Synopsis:
Some Salvia collectors want to obtain a broad range of sages including all the new introductions on the market. But Flowers by the Sea can't and doesn't want to grow all the new cultivars available, partly because there is a growing abundance of Salvia introductions. Instead, FBTS focuses on selecting the most superior new plants even when introducing its own hybrids in its series of Rainbow Jame Sages. Ask Mr. Sage is a regular feature based on calls and emails received by FBTS.

Synopsis:
Hummingbirds love the nectar of Salvias, particularly red ones, which they can see but bees can't. Also, unlike most birds, hummingbirds can taste sweets and seek out flowers that produce lots of sugary nectar. However, nectar can be difficult to come by during drought. The Salvia genus is well known for its bright flowers, rich nectar and many drought-tolerant plants. We suggest five bright red, drought-tolerant Salvias that hummingbirds love.

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
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.
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.
This plant reaches peak bloom during Spring or flowers for much of the season.
However, it may begin flowering sooner. Some Spring-blooming Salvias begin flowering in Winter; others start in Spring, keep producing color through summer and may continue on into autumn and first frost. Still others flower only in Spring.
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
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
(Red Velvet Mountain Sage) This is one of the most intense red-flowering variety of Mountain Sage we grow. Medium-sized flowers are profuse on this large, vigorous plant -- particularly in spring and fall. Dark stems and calyxes intensify the plant's drama along with glossy green foliage.
(Furman's Red Autumn Sage) Selected by noted Texas plantsman W.A. Furman in the 1970s, this hardy Texas native is beautiful and tough withstanding heat, drought and freezing winters. Its flowers, which bloom spring through fall, are a rich, saturated red bordering on magenta.
(Karwinski's Sage) From moist mountain areas in Mexico and Central America, this rugged, winter-blooming shrub is found in oak or pine forests at altitudes of 4,000 to 8,000 feet. This may account for this winter bloomer's ability to produce some bright, brick-red flowers even during short periods of freezing weather with temperatures as low as 20 degrees F.
(Windwalker® Royal Red Salvia) Salvia darcyi x S. microphylla 'PWIN03S' is one of the top 2015 plants for USDA Cold Hardiness Zone 5 selected by Colorado's Plant Select®, a nonprofit organization that focuses on promoting plants for low-water gardens.
(Elk Crimson King Jame Sage) Sometimes words fail us when trying to describe a unique new color. Definitely red, but with a clear blue overlay and a blue eye. Featuring masses of flowers that delight pollinators, this FBTS introduction is new for 2017.
(John Whittlesey Sage) Hardy, vigorous and long blooming, John Whittlesey Sage is a hybrid of D'Arcy's Sage (Salvia darcyi) -- a native of Mexico -- and Mountain Sage (S. microphylla), which is native to the American Southwest and Mexico.
