Marcus, Joseph A. (Austin, TX)

Leucophyllum frutescens (Berl.) I.M. Johnston

Cenizo, Purple sage, Texas ranger, Texas barometer bush, Texas silverleaf, Texas sage

Scrophulariaceae (Figwort Family)

Synonyms: Terania frutescens

USDA Symbol: LEFR3

USDA Native Status: Native to U.S.

A gray shrub with leaves densely covered with stellate, silvery hairs and bright pink-lavender, bilaterally symmetrical flowers borne singly in crowded leaf axils. Typically a compact shrub, 2-5 ft. tall, Texas barometer-bush or cenizo occasionally reaches 8 ft. in height, and 4-6 ft. in width. Leaves silvery gray to greenish, soft to the touch, up to 1 1/4 inches long but mostly 1 inch or less, tapering more gradually to the base than to the rounded tip, margins smooth. Flowers violet to purple, sometimes pink, nearly bell shaped, and up to 1 inch in length and width, appearing intermittently from spring to fall. Fruit a small capsule.

As one travels east across southern Texas near the Mexican border, the olive green of Creosote Bush (Larrea tridentata) gives way to the gray of this species, with its display of bright pink-lavender flowers. These burst into bloom for only a few days at a time, in the summer and fall, depending on rainfall. The ashy appearance of the leaves, also described as silvery, white, or gray, is due to the millions of tiny hairs covering them. A grouping of several individuals makes a good screen or hedge. There are many nice color selections and cultivars. This and other Leucophyllum species are popular water-conserving ornamentals in the Southwest.

Distribution

USA: TX
Native Distribution: In TX, Rio Grande Plain, s. Trans-Pecos, & Edwards Plateau, south to Nuevo Leon in Mexico
Native Habitat: Ditches, Ravines, Depressions, Hillsides, Slopes
USDA Native Status: L48(N)

Growing Conditions

Water Use: Low
Light Requirement: Sun , Part Shade
Soil Moisture: Dry
Cold Tolerant: yes
Heat Tolerant: yes
Soil Description: Rocky, well-drained soils. Limestone-based, Sandy, Sandy Loam, Medium Loam, Clay Loam, Clay, Caliche type
Conditions Comments: According to legend, cenizo tends to bloom in conjunction with rainfall. Cenizo is easy to grow so long as it has good drainage. Though this species is the most irrigation-tolerant of the genus, it is susceptible to cotton root rot if soil does not have good drainage and remains moist. Humidity and high night temperatures are lethal. Cenizos should not be fertilized or over-watered. Drought- and heat-tolerant. During very cold winters, may lose a few leaves.
Texas comments: Though native only from central and west Texas southward, this species has become widely used throughout the state. In areas of overly high rainfall and denser, moister soils, such as Houston and Dallas, this plant may require raised beds or amendments to improve drainage.

Propagation

Propagation Material: Seeds , Softwood Cuttings , Semi-hardwood Cuttings
Description: Plant seeds in greenhouse immediately after summer collection or store over winter in a cool, dry place and plant outside in spring, after final frost. Cuttings should be semi-hardwood and of the current seasons growth.
Seed Collection: Seeds are very tiny and must be collected before the capsule dries and splits open. Collect after each blooming period. Store in a cool, dry place.
Commercially Avail: yes
Maintenance: Prune plants to keep compact. The best time for planting most shrubs and trees is during the dormant period of fall and winter. As with any shrub or tree, the first year requires regular deep watering for successful root establishment. Once established, does not require fertilization or watering beyond average rainfall. Cultivated cenizos tend to become leggier with fewer blooms than in nature; tip prune to increase density.

Mr. Smarty Plants says

Question: Looking to replace Red Tips with major leaf spot infections. Need about third replaced. What suggestions would you have to replace these privacy hedge row type plants? Need a plant that will grow at least 5 feet tall. The plants are provided with water by a drip sprinkler system. Thank You.

Question: Hi.. I live in Southwest Austin and I am looking for a shrub that I can plant against the back of my house, which faces the north. I want something native, fairly low maintenance and not too large, as I would like them to be under the windows. I have several oaks in my backyard I get part-shade/part-sun. Thanks, Cindi

Question: I live in Austin in a neighborhood that is bordered on one side by highway 183 and on the other by MoPac and the train tracks. Even though I am least a three blocks from the closest highway, the traffic noise is horrific on all sides of my house, even at night. What might the best native plant or plants to put near the house to mitigate the noise coming inside and to plant around the perimeter of the property for the same purpose? I have a large yard, which I like, but I notice that the smaller properties, with smaller yards and close-by houses on all sides, are quieter because the buildings shield each other from the noise. Thank you for any suggestions.

Question: Hi! I have one (big!) bed in on the front of my house. Due to the way the house/motorcourt is built, that area (when it rains as much as it did last year!) doesn't drain well. I now have to replace some of my 'back ground' bedding plants. I am looking for something that grows 6-8 feet, and is evergreen. That part of the bed is in shade in the morning, but receives afternoon sun (not direct sun, however). It would also be good if it didn't require much water, as we are trying (very hard) to limit watering (for ecological reasons). All other plants (that survived) are native Texas plants. Bonus points if it has some time of color (berries, flowers, or changing leaves). I hope I haven't asked for too much!

Question: Is there some kind of drought resistant bush or thorny plant we can rim our property with to stop all the foot traffic through our yard? We don't care if it's pretty, just something thick and/or thorny to stop people wandering through our property day and night. We have over an acre lot which is near IH35 and would like some privacy. We have bamboo on one side which works nicely, but can this be transplanted to grow on the empty side of our yard? Thank you!
