How to Plant, Grow, and Care for Salvia Flowers

Print Friendly and PDF

Salvia (also known as “sage”) is a mainstay of the midsummer garden, providing long-blooming, aromatic flowers that are beloved by bees and butterflies. It’s practically a fail-safe perennial which is deer- and rabbit-resistant, too. Plant salvia this spring with our tips!

About Salvia

Part of the mint family (Lamiaceae), salvias provide colorful spikes of densely-packed flowers with tubular blossoms atop square stems and velvety leaves. Their flowers come in a range of colors, including purple, blue, red, pink, and white.

“Salvia” and “sage” are often used interchangeably; we tend to use “salvia” for the ornamental plant and “sage” for the culinary herb. However, garden sage has a few attractive ornamental varieties itself. 

Hummingbirds and butterflies love salvias’ tubular flowers and they’re adored by bees, too, so plant them if you wish to attract these pretty pollinators!

Fortunately, salvia does not tend to attract deer or rabbits. It is the distinctive, pungent odor of their leaves that acts as a repellent to garden pests.

Salvia are heat- and drought-tolerant, making them survivors in the summer garden. They grow 18 inches to 5 feet tall, depending on the variety. Salvias of all types can be grown in containers, too.

Take care when choosing salvias, because not all plants are hardy in all regions; some are best treated as annuals, but a number of perennial varieties are also available.


All salvias do best in full sun (6-8 hours of sunlight per day) and well-drained soil. Many varieties (typically those with light-colored flowers) will also do well in part-shade, but flowering will be reduced. 

When to Plant Salvia

  • Direct-sow salvia seed outdoors after all danger of frost has passed in the spring. See local frost dates.

How to Plant Salvia

  • Loosen the soil to a depth of 12 inches, removing any large stones or roots. Mix in a 3-inch layer of compost to provide nutrients.
  • If planting in a container, add some grit to the compost to improve drainage and feed in spring. Plants grown in a garden soil don’t need feeding.
  • Dig a hole twice the diameter of the container the plant is in.
  • Remove the plant from its container and place it in the hole so the top of the root ball is level with the soil surface.
  • Space plants 1 to 3 feet apart, depending on the variety.
  • Carefully fill in around the plant and firm the soil gently.
  • Water thoroughly.


  • Add a 2-inch layer of mulch around the plant to retain moisture and control weeds.
  • Water plants during the summer if rainfall is less than 1 inch per week. Salvia does not like excessive summer irrigation.
  • Salvia really doesn’t need feeding during the season.
  • To encourage continuous blooms throughout the season, deadhead spent flowers periodically.
  • At the end of the season, leave flowers on plants to encourage reseeding (and to feed the birds).
  • Some develop woody lower stems with age; feel free to prune this.
  • After the first killing frost, cut stems back to an inch or two above soil line. 
  • Divide perennial salvias every few years. The best time to divide is in early spring before new growth begins. Just lift, divide into clumps, and replant.
  • Every spring, apply a new think layer of compost, and mulch again.

Propagating Salvia

For the adventurous gardener, salvia cuttings can be taken in the spring or early fall.

Some salvias often self-propagate, so you might find seedlings you can use in other parts of your landscape!

Before flower buds have developed, take cuttings (remove stems) from vegetative (non-flowering) branches that are about 3 inches long. Remove the lower leaves and trim each cutting just below a node.

Insert cuttings into a pot of pre-watered compost. Cover the pot with a clear plastic bag—try to avoid the bag touching the foliage.

Place cuttings in a cool greenhouse and put up shading to prevent scorching from strong sunlight. After three weeks, cuttings should be ready to pot on.

Wit and Wisdom
  • The ancient Greeks and Romans used salvia as a memory enhancer.
  • The name Salvia comes from the Latin word salvere, which means “to heal.” Salvia has been used for its herbal and medicinal qualities since ancient times.

Pests and diseases are rarely an issue for salvia growers. Here are possible issues:
