Title: Drought-Tolerant Trees for South-Central Texas
Answered by: Dean Garrett
QUESTION:
I would like to replace two Golden Rain Trees with native ornamentals. They should be highly drought tolerant and should not exceed 25 feet in height. They will need to be tough since they will get little water from the hose once they are established. Do you have any suggestions? I live in the Hill Country north of New Braunfels.ANSWER:
There are several trees native to your area that are highly drought-tolerant and no taller than 25 feet:
- Prairie Flameleaf Sumac (Rhus lanceolata)
- Texas Persimmon (Diospyros texana)
- Texas Mountain Laurel (Sophora secundiflora)
- American Smoke Tree (Cotinus obovatus)
- Texas Redbud (Cercis canadensis var. texensis)
- Retama (Parkinsonia aculeata)
There are other trees native to your area that are drought-tolerant but may grow beyond your desired height, depending on soil and moisture:
- Western Soapberry (Sapindus saponaria var. drummondii)
- Anacua (Ehretia anacua)
- Texas Ash (Fraxinus albicans)
- Gum Bumelia (Sideroxylon lanuginosum)
- Bluewood Condalia (Condalia hookeri)
Since you didn't state whether the site is in full sun or shade, I assumed that it is mostly likely sunny. All these trees except Texas Redbud and Texas Mountain Laurel require full sun, but Texas Redbud can grow in either part shade or full sun and Texas Mountain Laurel can grow in shade but prefers full sun and will only bloom in full sun.
