Salvia is a large, diverse genus of the Lamiaceae (formerly Labiatae) family.
The Salvia plant belongs to the mint family (of which is the largest genus) with perennial representative species across the globe.
It is native to Europe, western Asia, and northern Africa.
Also known by its common names, including:
- Caradonna meadow sage
- May night meadow sage
- Meadow sage plant
The common sage Salvia officinalis is extensively grown as a culinary herb for flavoring and seasoning meats.
Salvia gets its name from the Latin word ‘salvere” which means “to feel well and healthy.”
Pliny the Elder is considered the first to describe the term ‘Salvia” by the Romans as a local anesthetic for the skin. [source]

Are Salvia’s Perennials?
There are 3 types of Salvia:
- Herbaceous perennials which die back to the ground at the end of the year
- Woody perennials like the sage used in cooking
- Annual Salvia
All hold some similarities in how they grow and bloom, along with their plant architecture. That is the long version.
The short version – Salvias are perennials and biennials.
Shrubs, from dainty to tall, leggy types, vary wildly in type, form, and shape. Salvia plants are upstanding, very easy to grow plants making them such a sight to see in landscapes.
The more popular Salvia varieties, Salvia leucantha, and Salvia splendens are native to the Mediterranean, California, and Mexico.
They generally thrive in dry and humid climates. In the garden, they lend a touch of vibrant hue come autumn and summer.
How To Care For Salvias?
Sage or Salvia brings a vertical accent with eye-catching flowers and fragrant aromatic foliage to the outdoor garden landscape.
Let’s look at what growing conditions Salvia needs to “show off” all their beauty.
Lighting: How Much Sun Does The Salvia Need?
Generally, perennial Salvias love the full sun (8-10 hours of direct sun) and can also do well with partial shade.
The best-growing location receives morning sun and afternoon shade. However, different Salvia species require slightly different light requirements.
They may also resist cold weather and the occasional frost.
Moreover, Salvias thrive in USDA hardiness zones 4 to 9, depending on the variety,
What Is The Best Soil And Fertilizer For Growing Salvia?
Salvias do well in any good garden soil and are drought-resistant to an amazing degree.
Salvia will tolerate poor soil fertility and drought conditions, but consistent water will produce better results.
Plant Salvia in spring after preparing the garden bed.
Use a tiller or garden fork to loosen the soil (12” to 15” inches deep).
Gradually incorporate 2″ to 4″ inches of rich compost or peat. Mix in a balanced slow-release fertilizer and fertilize weekly with a water-soluble 20-20-20 liquid fertilizer.
How Much Water Does Salvia Need?
In general, Salvia, once established, does not need a lot of water. However, this plant needs regular irrigation during its first growing season to establish.
Although Salvia does handle drought conditions pretty well during periods of drought, it provides supplemental watering to maintain soil moisture.
Avoid overwatering, as too much water can rot roots.
A good rule for watering Salvia growing in the ground is to water thoroughly and apply 1” inch of water every 7-10 days. (Include both rainfall and additional supplemental irrigation)
Applying water right at the soil level is easily accomplished using soaker hoses for deep watering.
Remember, Salvia plants growing in containers may dry out faster and require more frequent watering. Make sure any salvia does not sit in water.
If you find Salvias wilted in the evening after spending all day in the sun, they should recover.
However, if the plants are extremely wilted, you may want to give them some water at the base of the plants and not on the leaves. Water on the leaves may scorch them.
If you notice the potted plants wilted in the early morning, give the plants supplemental watering.
When Does Salvia Bloom and Does It Flower All Summer?
Salvia blooms throughout the early summer months allowing homeowners to add a wide range of flower color options from white, pale rose, vibrant red flowers, purples, and blue.
Flowering perennial salvias produce tall flower spikes of tiny, densely-clustered, rich in nectar flowers above the deliciously-scented foliage.
These plants grow anywhere from 18” inches to 5′ feet tall beauties, depending on the sage variety.
Aside from the remarkable aromatic foliage scent and magnificent blooms, the Salvia attracts some of the best neighborhood fauna while deterring some of the worst.
Deer Resistant Salvia
Animals such as deer, elk, and rabbits largely ignore Salvia. However, pollinators like butterflies, bees, and hummingbirds love the tall nectar-rich flowers!

The flowers of lighter-colored perennial Salvias can burn from the hot midday full sun of summer. Darker-colored flowers appear to be more sunburn resistant. [source]
Salvia Care – Planting
The Salvia, also called the “Meadow Sage,” produces some of the richest royal blue flowers to elegant purple blooms in May and June, all excellent additions to mixed perennial borders, rock gardens, and country-style gardens.
Other colors of the meadow sage flowers include orange, white, pink, cerise, and mauve, all interesting garden additions.
In short, the Silvia makes the perfect plant for putting on display borders, beds, and containers. Flowering profusely, the plant can survive droughts and the occasional neglect.
Its flowers provide joy to gardens and owners alike, requiring little maintenance or persuasion to grow during the summer months.
Carefully space plants 1′ to 3′ feet apart, depending on the variety.
As a general rule when planting salvia is to space plants twice the diameter of the pot, the Salvia came in.
Gently remove the plant from the container and place it in the hole, with the root ball level with the ground.
Pack in the soil around the root ball and firm it in, and water thoroughly.
After watering, I like to include a little liquid starter plant food for an initial boost.
Salvia Meadow Sage Plant Care and Maintenance
To keep Salvia compact and tidy, cut them back hard after flowering. Cutting plants down to 3”-4” inches to promote more growth and bloom.
Some varieties, after shearing, may potentially produce a second flowering.
During mid-summer, Salvia may begin to look overgrown and tired. Rejuvenate the plant by cutting back about ⅓ of the plant to encourage more growth.
Deadhead Salvia For More Bloom
To promote more flowers, deadhead spent blooms.
Select a good pair of hand pruners like the Felco #2 for the job and remove the old bare bloom spikes.
The typical Salvia branching is opposite each other along with a central leader.
When blooms begin to wither, remove the central leader and the opposite branches. This gives more room and promotes new growth and flowers.
Can Salvia Be Split or Divided?
Uproot and divide plants every few years. Early spring is the best time before new growth starts.
Salvia (sage) can grow quickly and re-establish itself when planting them in new areas.
For replanting, take a sharp spade to dig carefully around the plant’s edges.
Next, dig right through the middle, dividing the plant up into two clumps. Shake off the excess soil, then quickly replant the Salvia and water thoroughly.
Prune salvias down to its roots after the flowering season passes.
They can also be propagated via stem cuttings.
Keep your Salvia sage happy. In springtime, put a thin layer of compost and a 2-inch layer of mulch to control the weeds and retain moisture.
What Pests And Diseases Attack Salvia?
Salvia encounters the usual suspects in the garden. For continuous bloom, you need to protect them from these pests.
- Spider Mites – usually, leaves look a healthy green. If the tops of leaves begin to carry a grayish cast, look under the leaf for red spider mites.
- Aphids – black and green clusters on tender new plant growth sucking juices from plant cells. They secrete a sticky “honeydew” on the foliage. Homemade aphid control here.
- Whitefly – When the plant is brushed or bumped, whiteflies take off in a cloud, appearing like “flying dandruff.” Like aphids, they suck juices from plant leaves, buds, and stems to weaken the plant.
- Emerging at night, slugs and snails like acidic soil and moist, well-mulched gardens. Their file-like tongues leave hide holes in leaves.
- Overwatering can produce root rot.
- Powdery Mildew – Good air circulation helps to reduce potential foliar diseases like powdery mildew and problems.
Salvia Varieties To Consider For The Garden
Salvia ‘May Night’
The cultivate known as ‘May Night’ is a deer resistant, hardy 1997 Perennial Plant of the Year and is still a best seller.
Easy care, thrives in a hot sunny location, does well planted in groups. Beginning in May, the beautiful violet flowers emerge and hold through the summer.
After the “first bloom,” cut the plant back for a second bloom. Excellent companion plant to mix with other oranges and reds.
Also known as the sage of the diviners, grows in shady and moist locations. Salvia divinorum plant originally came as a native from the cloud forest of Sierra Mazateca, Oaxaca, Mexico.
As a psychoactive plant, some claim it causes spiritual experiences and hallucinogenic encounters. Moreover, it produces mainly through vegetation and releases a few variable seeds.

It grows up to three feet tall in cold areas, while those in warm regions may reach 6 feet of height. Hummingbirds love this salvia variety.
Desert blaze (Salvia greggii), also known as autumn sage, stuns guests in shops with its clusters of red flowers lying beautifully against its white-edged foliage.
Germander sage (Salvia chamaedryoides) is an easy-spreading groundcover with bright blue flowers – Drought tolerant.
Another interesting variety is Salvia cardiophylla. It blooms pale blue flowers, produces heart-shaped leaves, and grows very fast. Just make sure you provide well-drained soil so it can thrive in your garden.
The Winter-Flowering Salvias
There’s a little-known group of Salvia’s originating from the cool, mountainous areas of South and Central America. These species include:
- Salvia dorisiana
- Salvia conertiflora
- Salvia wagneriana
- Salvia guaranitica ‘Costa Rica Blue’
As such, the flowers complement to spring and winter seasons.
For these plants, the best type of environment is a moist and cool one. Shelter them from frost and hot winds by positioning them beside tall shrubs and deciduous trees.
Encourage new growth by cutting old canes during late summer, setting up new growth to time perfectly right from autumn to spring.
