With Salvia, There’s Something for Everybody

Salvia, a genus of plants in the mint (Lamiaceae) family with nearly a thousand members, is known for its toughness.

Heat tolerant, chill tolerant, drought tolerant, impervious to pests and disease, deer resistant — salvia takes a lickin’ and keeps on blooming beautifully.

“Because of their durability, salvias are something that everybody should have,” says Skip Richter, a county extension agent with Texas A&M Agrilife Extension Service. “Pick the right one for your area and it will be a durable plant.”

The large number of plants in this genus also means the options are wide open, in terms of selecting the right salvia for your garden.

“There’s a salvia for pretty much every part of the continental United States,” says Richter. “Find the ones that do well in your area and you’ll have a wonderful addition to your garden.”

Let’s learn more!

All Shapes and Sizes

With 900-plus types, you’d expect to encounter some variety – and you’d be right.

In this group, you’ll find perennials, annuals, semi-woody subshrubs, tall, flowy plants, and types that hug the ground almost like groundcover.

Flowers are available in a variety of hues: red, pink, white, blue, purple, coral, and yellow.

Some types appreciate full sun, and others do quite well in the shade. Some will fill the air with lovely fragrance, while others have no scent.

You’ll find salvias that do well in mass plantings, in borders, or in containers. And some give back by attracting pollinators such as butterflies and hummingbirds.

With such a large range of options, the tricky part is narrowing down which of this fabulous group you’d like to plant!

Let’s look at a few options:

Varieties and Where to Buy

One of my favorites is S. greggii, also known as autumn sage. This small, evergreen shrub produces flowers very early in spring and continues to flower profusely all summer long.

Find seeds for this variety from The Clayton Farm, available via Amazon.

S. Greggii Seeds

You’ll get a packet containing 30 seeds that will produce 1- to 2-foot-tall, loose shrubs that do well in zones 5b-10.

Another type beloved in Texas is Mexican bush sage (S. leucantha). This one can grow to 4 feet tall, displaying long purple and white flower spikes.

You can get a “starter plant” for this type online via Amazon.

This one does well in zones 8-11. You’ll get a plant described by the seller as well-rooted, in a 2 1/2-inch by 3 1/2-inch pot.

Frriendship sage (S. guaranitica ‘Amistad’) is a variety that does well in shady areas of my backyard in Central Texas, and that also flourishes in the upper midwest. At my house, this one freezes to the ground during cold spells, but is fast to regrow come springtime.

Small ‘Amistad’ plants are available via Amazon.

Butterflies and hummingbirds enjoy the nectar from this plant.

Scarlet sage (S. splendens) is hardy to zone 5 and is often grown as an annual in areas further north. Get seeds for purple, red, or burgundy — or a mix — from Mountain Valley Seed Co., available via True Leaf Market.

S. splendens of different shades of red and white grow very closely together. The sages have pointed fruits sticking out from the blossoms.

Plants grow about a foot tall and produce large flower spikes over dark green leaves.

Both the purple and white varieties of S. nemorosa do well in the northeast. You can get a live S. nemorosa ‘Snowhill’ plant from Uniquegardenus, available via Amazon.

You’ll get a one-gallon pot containing an organically grown plant.

Pacific Northwest gardeners might want to try S. microphylla ‘Hot Lips,’ available from The Clayton Farm via Amazon.

You’ll get a packet of 30 seeds harvested in 2017.

And we would be remiss if we didn’t mention S. officinalis, which is common sage, the type that we cook with. Nature Hills offers it in 4½-inch containers.

A large patch of common sage is in full bloom. The small, purple flowers are on tall stalks sticking up and out of the narrow, green leaves of the plants.

This plant grows to about 2 feet tall and 2 feet wide. Its flowers are purple-blue.

Get ‘em Growing

Where you plant your salvia will depend on the variety. Most like well-draining soils, so do keep that in mind. Average garden soil is fine for most varieties.

If transplanting from a nursery start, dig a hole twice as wide as the diameter of the pot, and the same depth. Remove the plant from the container and insert into the hole.

Backfill with removed soil and water well. “Add mulch around the planting area to hold in soil moisture and deter weeds,” says Richter.

If growing from seed, you can sow directly into the garden. Check the back of the seed packet — some varieties require light to germinate, and seeds should be spread on top of the soil.

You can also start seeds indoors six to eight weeks before the last frost.

If you wish to divide existing perennial salvia plants, the best time to do so is in late winter or early spring, before new growth begins.

A Little off the Top and Sides

To encourage bushy growth and lush blooms, many salvias do best with a pretty severe haircut a couple times a year. Do this once in late winter before blooming commences, and then again in early fall.

“Salvias tend to bloom at the terminal end of new growth,” says Richter. “Periodic shearing helps to extend the blooming season.”

Throughout the summer, clip bloom spikes after flowers have faded. This will also encourage more flowering.

Many of this group are quite drought tolerant, requiring no supplemental water, even in Texas summers. Others will wilt when they’re parched.

When it comes to feeding these plants, Richer says, “They don’t need a lot of fertilization. Look at your plant and see how it’s performing.”

If it looks like it needs a boost, “Use a turf-type fertilizer — one that’s heavier in nitrogen,” he says. “Don’t overdo it. Start at the lower end.”

Of course, Richter says, the best way to know if you need to fertilize is by performing a soil test. Many county extension services will analyze a soil sample for you.

Mite or Might Not?

Salvias are relatively problem-free. “In general, these are pest- and disease-free plants,” says Richter.

However, a few gardeners have reported seeing spider mites munching on their salvias. Get rid of these with neem oil, such as this one from Bonide, available via Amazon.

This 32-ounce spray bottle is ready to use.

If you’re trying to grow a selected variety in the wrong climate, you may see problems. For example, if a hot-weather type is grown in prolonged cool and wet conditions, you may see stem and root rot, or powdery mildew.

Ubiquitous Beauty

With a variety that’s suited to growing just about anywhere in the United States, durable salvia is a wonderful addition to many gardens.

It’s easy to care for and is not demanding when it comes to water, nutrition, or soil type. I usually have two or three types growing in my garden at any time, and you should consider adding some to yours.

About Gretchen Heber

A former garden editor for a daily newspaper in Austin, Texas, Gretchen Heber goes through entirely too many pruners and garden gloves in a year’s time. She’s never met a succulent she didn’t like and gets really irritated every 3-4 years when Austin actually has a freeze cold enough to kill them. To Gretchen, nothing is more rewarding than a quick dash to the garden to pluck herbs to season the evening meal. And it’s definitely time for a happy dance when she’s able to beat the squirrels to the peaches, figs, or loquats.

I just planted my 1st garden and used a few of the maynight and pink salvia. I am having trouble with the pink ones. They look like they are dead and not doing well. I thought maybe it needed watered but that’s not doing the trick. Please help or ideas/tricks that I might be able to try. I am going to try and cut them to see if that helps!
