Salvia glabrescens 'Elk Yellow & Purple'

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.

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.

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.

Try this plant to control weeds, limit erosion, conserve soil moisture and add color to your landscape.

From short perennials that form dense mats spread by underground stoloniferous roots to thickets of medium-size shrubs, many Salvias are efficient ground covers.

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.

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.
