Season of bloom: Summer to the first frost
Plant type: Herbaceous perennial or annual
Height: 1 to 3 feet
Scarlet sage is native to Brazil and is a perennial plant, but it is often grown annually in colder climates. During its long blooming season, this salvia plant produces flowers in shades of burgundy. However, you’ll often find cultivars in other colors: pink, blue, lavender, orange, and white are a few.
Scarlet sage is a low-maintenance plant that is easy to care for. It thrives in a spot that gets plenty of sunshine or partial shade. To keep your plant happy, ensure the soil drains well, as excess water can cause health issues.

Mealycup sage is native to south-central America and northeast Mexico. This blue-purple salvia produces attractive spikes and small flowers. The blooming season of mealycup sage starts as early as spring and goes late into the autumn, keeping your garden colorful for months.
Plant mealycup sage in well-drained, moist, or clay-rich soil. Prune after the blooming season. Water the plant every 10 to 14 days during the growing phase or more often if it’s scorching hot. Also, don’t hide it in the shade—it loves full sun!
Baby Sage (Salvia microphylla)

Plant type: Evergreen shrub
Height: 3 to 4.5 feet
Although baby sage is native to southeastern Arizona and the mountains of Mexico, its species readily hybridize, resulting in numerous cultivars. You will enjoy baby salvia’s red, pink, and white blossoms in spring, with a second bloom in fall. A tip: use its aromatic leaves for tea.
You should plant baby sage in well-drained, fully organic soil with good sun exposure. It is drought, heat, and salt-tolerant species.

Season of bloom: June to August
Plant type: Biennial or short-lived herbaceous perennial
Height: 2 to 5 feet
Clary sage is a plant that originates from the Mediterranean region of southern Europe to central Asia. It blooms in fragrant, showy white-lavender blossoms and is a perfect pollinator to complete any garden. Clary sage is also edible and herbaceous; most butterflies find them very attractive.
Salvia sclarea is a drought-tolerant plant and requires little watering. It prefers full sun and well-drained, sandy soil. Just don’t over-fertilize the soil, or you’ll get tall plants with few flowers.

Gentian sage, a plant native to a vast region of central Mexico, boasts of beautifully blue salvia flowers with a green calyx, making them quite appealing to the eye. While it can tolerate droughts, frost will kill these species.
Gardeners consider it an annual plant because it is sensitive to hard frost. However, Gentia sage roots can be easily lifted from the ground and kept in a greenhouse during winter. The plant generally thrives in full sun and requires well-drained, humus-rich, moist soil that is not overly soggy.

Season of bloom: Early summer to the first frost
Plant type: Ornamental perennial or annual
Height: 1 to 3 feet
As a native to Mexico and southeastern America, Texas sage is perennial in warmer and annual in colder climates. The bright red flowers are often confused with the pineapple sage, which is edible. However, the Texas sage is a purely ornamental plant with a prolonged blooming season.
The best place to grow Texas sage is full sun to partial shade in sandy, fertile, or clay soil with good drainage. It can withstand drought, but if you water it during the dry, it will bloom in abundance.

Season of bloom: Fall to winter
Plant type: Semi-evergreen perennial
Height: 4 to 7 feet
The forsythia sage is native to the mountains of Mexico and blooms later than other plants. It produces yellowish flowers that can bloom as late as winter, provided it’s warm enough. The forsythia sage’s blooming season can vary depending on climate, with a shorter season in colder regions and a more extended blooming season in frost-free areas.
Forsythia sage grows best in full sun but appreciates some afternoon shade during extreme heat and prefers well-draining soil that is kept moist. We recommend watering it more frequently during dry periods.
Russian Sage (Salvia yangii)

How to Plant Salvia?
If you’ve been fascinated by the stunning beauty of salvia plants and have read up on the various types and care instructions, you might want to try growing one in a garden or container. It’s a great way to enjoy their mesmerizing beauty up close and put your knowledge to practice!
How to plant
Salvia can be propagated by seeds or cuttings. You can spread the seeds over the top of the soil or cut a stem and dip it into the soil to germinate.
When to plant
Plant salvia seeds indoors in late winter or early spring, about six to eight weeks before the last frost. Then, transplant them outdoors. You can also plant salvia seeds or plants in late spring or early summer.
Where to plant
Plant salvia in a sunny spot and well-drained soil in your garden or containers. Salvia plants are drought-tolerant and thrive in warm climates.
How to water
Water salvia plants until the soil is evenly moist. Keep it moist until the seedlings emerge—around two weeks.
How Do You Prevent Salvia from Weeds?
While salvia is immune to slugs, it may still be affected by weeds that compete for water, nutrients, and space. Here are some tips to prevent salvia from weeds:
Mulch the soil. Mulching helps to suppress weed growth, retain moisture, and improve soil quality.
Weed regularly by hand. Weed your salvia garden in the spring and summer before the weeds start seeding.
Apply a pre-emergent herbicide. The best time to apply herbicide is before the weeds have a chance to germinate.
Avoid over-watering and fertilizing. Water only when the soil is dry, and use balanced fertilizer once in the spring to avoid weeds.
Landscape Design Tips
Pairing salvia with other plants is a highly effective way to design your garden. Companion plants benefit each other in many ways, such as repelling pests, contrasting the flowers, or improving soil health.
If you’re keen on growing salvia, adding a few companion plants is ideal for most salvia species.
A. Lavender. Lavenders thrive in well-drained soil and full sun. Like salvia, they’re often grown for their aromatic foliage.
B. Legumes. Legumes can fix nitrogen from the air and add it to the soil, which boosts salvia’s growth and flowering.
C. Ornamental grasses. Like salvia, ornamental grasses thrive in full sun, adding a beautiful contrast to the spiky salvia flowers.
D. Yarrow. Yarrow releases copper, phosphorus, and other nutrients into the soil when it decomposes, attracting beneficial insects and repelling some pests.
FAQ
Now that we’ve covered some of the most popular salvia varieties you can bring to your garden, let’s look at some of the common questions relating to these flowering herbs.
Are All Salvias Edible?
No, not all salvia species are edible. Some ornamental salvias are best kept off your dinner table. They aren’t poisonous but have a strong and bitter flavor that isn’t particularly pleasant. The edible salvias are commonly called sage, like the common Salvia officinalis.
Salvia can be used in various forms, such as fresh or dried, in tea, as an extract, oil, or tincture. However, some types of salvias, such as salvia divinorum, have psychoactive effects and are illegal in some countries.
What Are the Benefits of Salvia?
According to the European Medicines Agency, salvia has a lengthy history of medicinal use in ancient Egypt, Greece, and Rome, later spreading to India as well. Sage is known for its antispasmodic, antiseptic, astringent, and antihidrotic properties. It was often used to improve fertility, stop bleeding, alleviate hoarseness and cough symptoms, and enhance memory functions.
Besides their medicinal benefits, different salvia species produce beautiful flowers that attract pollinators, making them a great addition to your garden. You can choose from early to late-blooming varieties or even ones that bloom for an extended period.
What Is the Benefit of Salvia Root?
According to WebMD, salvia root, also known as Danshen, is a herb used in traditional Chinese medicine. While the evidence on the topic is scarce, it is believed to improve blood pressure and heart health, as well as support wound healing.
The root, just like the salvia plant leaves, can be taken as a tea, extract, oil, or tincture. However, it may interact with some medications. You should always consult your doctor before using salvia root for any purpose.
