Tweedia caerulea

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 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 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.

In the right locale, this plant survives and thrives despite minimal summer water.

Drought resistance is an important characteristic of xeriscapic – dry landscape – plants, a category that includes a multitude of Salvias. Many low-water Salvias are native to parts of the world with little rainfall all year or regions where summers are dry and winters are wet.

Nevertheless, there are also drought-resistant Salvias for places such as Florida where winters are dry and summers are wet.

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.

This plant reaches peak bloom in Summer or flowers for much of the season.

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

There is a great deal of overlap in blooming seasons for Salvias.

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.
