Highlights

Texas mountain laurel sends out gorgeous fistfuls of purple flowers in the spring that attract pollinators (and people.) The smell of Texas mountain laurel flowers has been compared to grape Kool-Aid in several gardening books. They are easy to grow and, over time, can turn into small 20-foot trees.

Texas mountain laurel has been called “one of the ten best ornamental shrubs in the nation.” They are a stunning addition to any yard or park in the southwestern United States. Find planting tips below.

Texas mountain laurel​ vs. mountain laurel

Many species of mountain laurel native to America roughly fall into either the “Texas mountain laurel” or “mountain laurel” group. (If you’re worried about which is which or looking for a specific plant, writing down the Latin name of the type you want will be a huge help. See below for their Latin names!)

Both Texas mountain laurel and mountain laurel:

These species of mountain laurel are native to the eastern US. Shrubs in this species group have tiny flowers shaped like algebraic equations. You’ll know you’ve got the right plant if the Latin name starts with Kalmia. Learn more in our Meet mountain laurel.

Why Texas mountain laurel matters

George O. Miller, in his book Landscaping with Native Plants of Texas, calls Texas mountain laurel “one of the ten best ornamental shrubs in the nation” and describes how “showers of vibrant purple flowers cover the plant and perfume the air with the scent of grape Kool-Aid.” That’s not a gentle floral scent. It’s grape candy. Walk past a blooming Texas mountain laurel and you’ll stop, look around, and wonder who spilled something. The flowers are the show, and they happen in February through April, when most of the landscape is still brown and dormant.

This is a pollinator’s dream

The flowers attract honeybees, native leaf-cutting bees, and hoverflies, all of which crawl inside the pea-shaped blooms to reach the nectar. Texas mountain laurel is also a host plant for Henry’s elfin, a small, brown butterfly whose caterpillars feed on the flower buds and young leaves. Henry’s elfin uses different host plants in different parts of its range, but in Texas, this is one of its go-to plants. If you see tiny green or reddish caterpillars on the buds in spring, leave them alone. They’re doing exactly what they’re supposed to.

And then there’s the cultural history, which goes back at least 6,500 years. The bright red seeds, called mescal beans, have been found in archaeological sites across the Lower Pecos region of Texas. At least twelve Indigenous nations, including the Apache, Comanche, Pawnee, and Wichita, used the seeds for adornment, ceremony, and as rattles in dances while still in the pod. This is a plant with deep roots, in every sense.

Texas mountain laurels can go from bush to small tree

You can prune a Texas mountain laurel over time to be more in the shape of a tree than a bush. It will still make its purple Kool-Aid flowers and remain evergreen, even as it gets tall. Texas mountain laurels grow up to two feet a year.

Beginner tip

Texas mountain laurel is evergreen, so it never goes bare. That makes it an excellent choice for spots where you want year-round screening or green backdrop, like along a fence line or against a house wall.

How to grow Texas mountain laurel

Soil

Alkaline, rocky, well-drained. This plant evolved on limestone hillsides and it wants soil that reflects that.

If you garden in the Texas Hill Country, your native soil is probably perfect. If your soil is heavy clay, make sure it drains well; Texas mountain laurel will not survive in waterlogged ground. It doesn’t need rich soil. In fact, it prefers lean, rocky, chalky conditions.

Planting card

Texas Mountain Laurel

Dermatophyllum secundiflorum

Sun

Full sun is ideal and gives you the most flowers. It also handles part sun, since it naturally grows as an understory plant beneath taller trees. In part sun, expect slower growth and fewer flowers, but the plant will still look good and stay healthy.

Water

Texas mountain laurel handles drought with ease after it’s established, which normally takes the first year. Water regularly during the first year or two while the roots get a foothold, then back off. Overwatering is a bigger risk than underwatering with this plant. If you’re in a spot that gets regular rainfall, make sure the drainage is excellent.

A note on Texas mountain laurel seeds

Sadly, Texas mountain laurel seeds are poisonous. The seeds themselves reside inside a hard seed coat (it’s almost like a big peapod.) This hard seed coat helps give some protection from easily accessing the poisonous seeds found inside.

This native plant is best planted away from children and pets.

What to grow with Texas mountain laurel

Texas mountain laurel wants alkaline soil, full sun, and minimal water. Pair it with other natives that share those preferences:

Where can I buy Texas mountain laurel?

Most big-box garden centers don’t carry true natives, but Texas mountain laurel is easier to find than you might think. Your best bets are a native plant nursery near you, a native plant society sale, or a trusted online grower that ships to your region.

FAQs

How fast does Texas mountain laurel grow?

Slowly. Expect 6 to 12 inches a year in the early years. Growth speeds up once the plant reaches about 5 to 6 feet tall. A mature Texas mountain laurel can eventually reach 15 to 20 feet, but that takes many years.

Can I grow Texas mountain laurel in a container?

Yes, and it actually does well in large pots, especially when you can control the soil (alkaline, well-drained). It’s a great option for patios and pool areas where you want the spring fragrance up close.

Will it grow OK in acidic soil?

Not well. Texas mountain laurel evolved on limestone and strongly prefers alkaline soil. If your soil is acidic, this isn’t the right plant for your yard. Try other evergreens like native pines, instead.

Plant nerd fact

This plant recently got a new name.

You’d think a plant’s Latin name is settled forever, carved in stone by some botanist in a powdered wig, hunched over a candle. Not so.

For over 200 years, Texas mountain laurel was known by the Latin name Sophora secundiflora. Then in the early 2000s, scientists took a closer look at the chemistry inside its leaves, found an alkaloid fingerprint that didn’t match anything else in the Sophora genus, and created a brand-new genus for it: Dermatophyllum. Two centuries of textbooks, rewritten in just the last few decades because of a chemistry test.

You may still encounter this plant in nurseries or gardens called by its old name, but now you know: it’s the same plant. Latin names sound permanent, but plants get reclassified all the time.

Texas mountain laurel is one of those plants that does a lot with very little. It stays green all year, blooms purple every spring, fills your yard with the smell of grape candy, barely needs water, and handles the worst heat and drought Texas can throw at it. It’s slow, but it’s worth the wait.

Plant it alongside American beautyberry, agarito, blackfoot daisy, and red yucca for a drought-smart native garden that looks great in every season.
