Texas Sage
Leucophyllum frutescens
Silver-leafed desert shrub that bursts into purple blooms after rain.
Care Instructions
Water deeply once a month once established. More water in the first year only. Overwatering is fatal — this plant evolved for desert conditions with excellent drainage.
Full sun only (8+ hours). Will not thrive in shade. Reflected heat from walls or pavement is beneficial.
Rocky, sandy, or caliche desert soils. pH 7.0–8.0. Never amend with compost or add fertilizer — rich soil causes root rot and death.
Seasonal Guide
Best Planting Time
Fall (September–November) in desert regions — gives roots time to establish before summer heat.
Bloom / Growth Season
Flowers profusely after monsoon rains or high humidity events (hence the nickname "Barometer Bush"). Peak bloom July–October.
Dormancy
Evergreen in zones 8–10. May lose some leaves in a hard freeze but recovers quickly. No true dormancy in mild winters.
Common Problems & Solutions
Root rot from overwatering or clay soil
Ensure perfect drainage. Plant in raised beds or rocky slopes. Once root rot starts, the plant rarely recovers — prevention is essential.
No blooming despite good care
Stress triggers flowering. Reduce watering to once a month and expose to full sun. Too much comfort = no blooms.
Cotton root rot in heavy soil
Improve drainage dramatically. Plant in a 12-inch raised bed of sandy soil.
