How Tall do Red Salvias Grow?

These 2-4 feet tall plants spread up to 2 ½ feet wide.

The leaves are a shade of medium green, hairy, roughly triangular, and have scalloped edges. While the opposite leaves may vary considerably in size, they have long petioles coming off the square stems.

Its dark-green, heart-shaped leaves emit a fragrance that drives away mammalian pests, making them deer and rabbit resistant.

The stems are an upright, terminal, racemose inflorescence that grows up to 10 inches long.

The flowers are produced in loose whorls vertically on the stem.

The Red Salvia flowers are tubular shaped and emerge from deep red calyxes, present in tall spikes.

This species attracts hummingbirds who regularly show up for a feast, as it is perfectly designed for pollination.

It is ideal for placement in medium to large containers as well as in gardens and landscapes.

Advantages of Growing Red Salvia

Depending on the usage, people often refer to the Red Salvia as Red Sage, which has several proven medicinal uses.

To begin with, you can use fresh leaves to create an extract. You can then infuse these extracts into drinks.

When prepared as Red Sage, Red Salvia has several health benefits.

It contains high nutrients such as vitamins and minerals, such as small amounts of magnesium, zinc, copper, and vitamins A, C, and E.

It also has minimal doses of caffeic acid, chlorogenic acid, rosmarinic acid, ellagic acid, and rutin.

Besides this, it is also loaded with antioxidants since it contains over 160 distinct polyphenols or plant-based chemical compounds.

Its antimicrobial effects can neutralize microbes that promote dental plaque.

It was and is traditionally used to ease menopausal symptoms as well as diabetes.

Red Salvia Plant Care

The Red Salvia is a comparatively easy plant to grow; however, it does require continuous maintenance depending on which area you live in.

Since it thrives in warmer climates, you need to take extra care when growing them in colder areas.

This plant grows very quickly; you will have to constantly replant, prune and propagate the seeds to prevent them from spreading wildly.

Growing Red Salvia

Watering Red Salvia

The Red Salvia thrives best in consistently moist soil. You must be careful of overwatering them as it can cause the roots to rot.

The best action is to prepare a watering schedule every seven to ten days.

This is sufficient for the plant to grow. Depending on the amount of rainfall and hot daytime temperature, you can alter your schedule.

Check whether the first inch or two of soil is dry before watering.

If the soil is dry, then water deeply to ensure that the water reaches the plant roots.

Normally, annuals like the Red Salvia have fairly shallow root systems, meaning that they dry out faster than well-established perennial plants and shrubs.

Light for Red Salvia

The Red Salvia successfully grows in areas that receive partial shade.

So you can plant them under shady trees.

If your trees are west-facing, then your plants will thrive underneath.

This plant ultimately grows best and blooms better if it receives longer hours of sunlight.

So you can also plant them in large containers on the porch facing west.

Ensure that your garden beds do not have other larger plants that might prevent the Red Salvia from getting enough light.

If the Salvia gets at least six to eight hours of bright sunlight per day, then you will have a healthy blooming plant.

Soil for Red Salvia

Plant the Red Salvia in moist, well-draining soil.

If you have a loamy mixture that is rich in organic matter but doesn’t get boggy or retain too much water, then it is the best combination for the plant.

You can externally amend nutrient-deficient soil with organic matter before planting.

To retain the moisture, add mulch to the top layer of the soil, especially during the hotter summer months.

Temperature and Humidity for Red Salvia

The Red Salvia plant is fairly temperature-sensitive and prefers to be grown in a consistent soil temperature.

Since it is not frosting tolerant, You must not subject it to temperatures below 32 degrees Fahrenheit.

Although the Red Salvia does not have any special humidity requirements, it grows best in high humidity areas and remains warm throughout the year.

However, in USDA Hardiness Zones 9 – 11, you can grow it as an annual in cooler areas.

Red Salvia Plant in Pots

Use moist to slightly dry soil when you are potting or repotting the Red Salvia plant.

Water them regularly, maybe once or twice per week during the dry season.

Remove weeds or apply a 2-3 inch layer of mulch for a tidy appearance.

Since the Red Salvia is a heavy seeder, place it in an area where it re-seeds easily and return it each year.

You can transplant them from the beds to the pots or containers after the reseeding.

Bring them out or transplant them once the seeding season is over and the plant begins to emerge.

Propagating and Pruning Red Salvia

You should ideally propagate Scarlet Sage Salvia through seeds.

When indoors, sow the seeds in a pot for 6 to 8 weeks before the last frost date of late spring.

The temperature range should be between 72° – 75° degrees Fahrenheit.

Water lightly as the fine seeds can wash away or penetrate too deeply into the soil.

After the last frost date, transform Salvia into the garden beds by spacing them 10-20″ apart.

This allows for more room to grow and show off their bright blooms.

To branch them out better and cut off the tip of each stem, this results in two new stem tips that are produced from the axils.

If you grow the Salvias during the fall, pinch back the stem tips until around June.

Cutting back delays flowering, so you can use this method depending on when you want it to bloom the most.

Prune the woody stems down to the lower set of new leaves. Prune the softer brittle stems to the ground.
