(Prairie Sage) Native to a large part of the central United States, this perennial Salvia is a beloved wildflower, delighting us with large cerulean blue flowers. Hummingbirds and butterflies love it as well.
In full sun with good soil, this sage provides a spectacular floral display from late summer through fall. We like to plant it among other perennials and shrubs, where it can poke its head out here and there. It's a reliable addition to any garden designed to attract pollinators and the human eye.

I planted three of these last fall and was impressed with how nice they looked when they arrived. I watered them diligently and they did well until winter hit. We get rain but we also get wind in my Zone 8b Pacific Northwest garden by the coast. None of the three Salvia azurea plants made it through the winter unlike a dozen other salvias I planted last fall. I waited until May before giving up on them. I was a bit surprised because this is listed as being for Zones 5 - 9, and coming from the prairies of the midwest, so I expected it would handle our mild winters but strong winds well. But no such luck - perhaps it needed more time in the ground before winter?
FBTS Notes:
This species is native to areas with dryish winters, or where the soil is frozen. Wet soil in the dormant season along with moderate (above freezing) temperatures can be difficult for this species.

Creating a butterfly garden is like creating a teen-friendly home. You need to offer tasty snacks, healthy beverages, and comfortable accommodations that aren't too tidy. Like the teens that fill your basement and backyard, butterflies will keep coming back if you give them what they need. The variety of plants in your yard is the main reason why butterflies do or don’t visit. Salvias are among the popular plants for adult butterflies that love nectar.

Blue Salvias bring peace to flower gardens. True blues, such as West Texas Grass Sage (Salvia reptans), are especially eye-catching. The same anthocyanins that make berries a healthy dietary choice also give them their colors. Similarly these chemicals create the wide variety of blues, purples and reds in the petals of flowers such as Salvias. Flowers by the Sea offers six varieties of tough Texas sages that can help you create a soulful garden bursting with blue. Drought-resistant and long-blooming, they grow happily in USDA plant hardiness zones 8 to 9, with some flourishing in areas as cool as Zone 4 and as hot as Zone 11.

Florida is one of the wettest states in the nation, yet it is a fine place to grow Salvias if you select shade-tolerant, moisture-loving species and ones native to Florida. Gardeners who are accustomed to growing Salvias in a dry climate face a variety of surprises in Florida gardens. These include recurrent periods of drought, many cloudy days and soil that is so poor it has to be amended for Salvias.

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.

Salvias that grow well in Florida may behave differently from one region of the state to another. This may mystify gardeners who have just moved to Florida or have moved to a different area in the state. Based primarily on seasonal variations in temperature, the four main regions are North, Central, South and Tropical Florida.

Here are some guidelines for success with this plant in your garden.
Click on an individual icon for more detailed information.
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 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.
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.


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.
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.
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.
