What does Texas Mountain Laurel Look Like?

Texas Mountain Laurel is a multi-trunked tree that can be grown as a large shrub or a small tree. It is a slow grower that typically reaches 10-15 feet tall.

It is known for its evergreen dark green leaves, dense foliage, and beautiful clusters of purple flowers in the spring. The flower clusters can be six inches long and resemble wisteria flowers.

In the summer the tree has brown seed pods which contain bright red seeds. These seeds (also called beans) were used by Native Americans for ceremonial use and jewelry. However they are very toxic and a single bean can kill an adult if chewed. So never eat them!

5 Reasons to Plant a Texas Mountain Laurel Tree

1. It’s a great native evergreen plant

It isn’t easy to find a lot of native evergreen plants to add to your yard, but Texas Mountain Laurel is a a great one! It can be grown as an evergreen shrub or small tree for tight spaces.

This smaller, slow growing tree can add evergreen color to your landscape with its dark green foliage.

This ornamental tree can be used as a focal point of a landscaping bed, or plant several Texas Mountain Laurel trees together to create a privacy screen.

It’s also an excellent alternative to non-native invasive evergreen shrubs and trees such as Ligustrum (Privet).

2. Its spring blooms are unmatched

Early spring is when this Texas native tree really shines. Its large clusters of flowers droop from the trees from March to mid April.

For even more spring beauty in your yard, plant this tree alongside a Texas Redbud tree, which is covered in magenta purple blooms in March.

Texas Mountain Laurel blooms best in full sun, so it is a great tree for landscaping a sunny area.

3. Texas Mountain Laurel is very drought tolerant

Looking for an excellent low water plant once established? This tough plant actually thrives in dry rocky soils and the hot summers of Texas. It prefers alkaline soil and full sun conditions.

This tree requires good drainage and little more. Talk about the perfect tree for a low maintenance xeriscape yard!

4. It is a great spring nectar plant for your yard

Bees and butterflies are also drawn to the intoxicating grape scent of the flowers. The early spring blooms provide nectar and pollen while other flowering plants are still dormant.

Having a variety of plants in your yard with different bloom times throughout the year is critical for supporting pollinators.

5. It is a caterpillar host plant

It is also important to have butterfly and moth host plants in your yard. These are the plants that their caterpillars can eat. The Texas Mountain Laurel is the host plant for the Genista Broom Moth. The Genista caterpillar can eat the leaves which are toxic to other animals.

While many people see the Genista moth caterpillars as pests to get rid of, they are an important part of the food chain. Birds and lizards eat them, so don’t remove them unless you absolutely have to! The tree will bounce back from being eaten by the caterpillars.
