But with that said, the Texas mountain laurel tree has undergone several scientific name changes that we will discuss later.
As with the name changes, the shrub itself is not too difficult to care for, and we are here to help you successfully care for these shrubs.
More About Dermatophyllum Secundiflorum
The Texas mountain laurel used to fall into the Sophora secundiflora scientific name category but is now Dermatophyllum secundiflorum. It is a flowering shrub and are native plant in the southwestern United States and northern Mexico.
Still, it would be best not to confuse 🙃 it with Kalmia latifolia, also called the mountain laurel with other names Texas mescal bean, mostly from western Texas.
In the blooming season, the trees are filled with brightly colored flowers in lavender, purple, and periwinkle. It has a luscious scent to some people, like grape Kool-Aid similar to the heirloom German irises.
The panicles resemble wisteria as the color and shape appear as early spring blooms, followed by red seed pods in summer.
Gardeners mostly grow the Dermatophyllum secundiflorum as shrubs, but you can train them to grow into small trees.
It is a native evergreen that remains attractive with slender oval leaves with a smooth leathery texture. The bark is smooth, and the dark green foliage stands out in the garden.
According to history, Native Americans had ceremonial use but replaced it with peyote. The red seeds have a deep color and are used for making beads 📿 in jewelry.
Still, the tree’s seeds and other parts are highly toxic. The small tree grows with a deep root system and forms dense foliage ideal for growing as a hedge.
Furthermore, the tree is deer-resistant; any garden’s blossom-rich fragrance is a highlight.
Types of Texas Mountain Laurel
When it comes to these cultivars, not many exist. Still, a few experiments have been done; one of them is called the Silver Pesco. The cultivar, with its silver variation, is more resistant to the damage done by caterpillars. You can find a white flowering cultivar as well.
Texas Mountain Laurel Tree Care
Whether you grow the Texas mountain laurel as a small tree or privacy screen, it provides you with low maintenance once established.
It even looks beautiful in the front entryway. But it is a slow-growing tree to grow multi-trunked or with a single trunk.
The blooms appear in spring, and pruning needs to be done late in the growing season and needs to be done mindfully.
Texas Mountain Laurel Trees Lighting Needs
Whether grown in tight spaces such as a multi-trunked tree or a large shrub, please provide them with full sun to part shade. For planting in semi-shade areas, please provide them with some afternoon sun.
Sophora Secundiflora Soil
These native plants can tolerate different soil types. Whether you provide your shrub with rocky soils or decide on limestone soils, drainage is important. The Texas mountain laurel is tough, but well-draining soil is vital.
Water Regularly
With its drooping clusters and dark green leaves, the shrub is drought tolerant to use as low-water 💦 plants in the garden. Overwatering can result in rapid growth, causing the terminal clusters to become weak and break.
Texas Mescal Bean Sophora Temperature and Humidity
The Texas mountain laurel is a tough plant that can withstand a lot of heat and sun; it is drought tolerant but does appreciate some rainfall. It thrives in desert native regions but does need good drainage. However, too much humidity can become a problem as it decreases the vigor when new growth begins.
Fertilizing Texas Mountain Laurel
You only need to fertilize the large shrub when it lacks nutrients. Furthermore, overly rich soil can also be a problem as the small tree grows too fast, causing the lower branches to become weak, and it will not be able to support the flowers. You can add some calcium to help your plant become established.
Pruning Texas Mountain Laurel
The Texas mescal bean benefits from spring pruning to ensure it grows strong branches and helps form a pleasing shape. Once your small trees mature, you only need to remove dead or damaged branches.
You can shape your small tree into a shrub, but little pruning is needed for training it as a tree. You need to start trimming the plant when young.
You can do this by trimming the side growth. Also, be extra careful not to damage the main branches, as they will recover slowly.
Propagating Texas Mountain Laurel
With the slow growth rate and wanting to make an instant statement in the garden, we recommend investing in a Texas mountain laurel specimen instead. It does not propagate well when using cuttings. But if you have the patience, you can use the seed pods to grow your tree.
Still, the seeds can take years to germinate as they develop hard pods. But there are a few tricks up our sleeve to help.
Pick the pods when green before it turns dark brown to gray.
The pods will be soft with pale pink seeds.
Fill a gallon-sized pot with enough drainage holes with well-drained soils.
Also, water the soil often when the seeds are sown. Alternatively, you can directly sow them in the ground. Ensure to bury the seed about a 1/2 inch deep.
Now all that is left is patience 🙄. But if you received hard old pods, soak them in water to help break them apart. Whether you buy or get seeds from someone, you must scarify them before planting them.
You can do this using a knife or sandpaper. On the other hand, you can soak them in warm water for a day or two but keep changing the water out with tepid water.
A great approach is to make a small cut in the outer shell before doing this.
Common Pests and Plant Diseases
Young trees can become susceptible to the genista broom moth that loves the leaves and is mostly cosmetic. You can remove them with a water spray using a garden hose. Another problem is caterpillars which happen when you overfertilize your tree.
