- Description

Texas Ranger is a flowering, evergreen shrub in the snapdragon family and native to the Chihuahuan deserts of Mexico. It has a branched and compact habit, forming a rounded mass, 3 feet by 3 feet, at maturity. It has velvety silver leaves and small lavender flowers. Flower bloom is typically triggered by rains or significant soil moisture. The common name, sage, is sometimes given to this plant, but it is not a true sage. The genus name comes from the Greek leucos and phyllon meaning white referring to the whitish foliage. The species name honors Ida Kaplan Langman, a twentieth century American educator and plant collector.
Texas Ranger is especially drought tolerant and thrives in gritty, well-drained, alkaline or gravelly soils, with minimal moisture and full sun. Good drainage is essential. In areas of high rainfall, consider using raised beds.
These plants prefer low humidity, but have excellent tolerance for drought and heat. Applications of fertilizer are not recommended and, once established, the plants require minimal maintenance. Texas Ranger can be pruned to control the sprawl that comes with age. The plant can be used as an accent, informal hedge, or in xeriscape (waterless) landscape designs
Diseases, Insect Pests, and Other Plant Problems:
No serious insect or disease problems. Cotton root rot can be an issue.
