Langman's Sage
Leucophyllum langmaniae
A lush green sage with spring blooms that attract butterflies and hummingbirds, offering a softer look than silver-leaved varieties.
Hardy in USDA zones 8-11; a Chihuahuan native tolerant of mid-desert frost and extreme low-desert heat, evergreen and reliably free-flowering.
AMWUA Notes
A drought-tolerant green-leaved sage prone to overwatering rot; the most dependably blooming Leucophyllum, best thinned rather than sheared.
Care Guide
Drought tolerant once established and rot-prone if overwatered; deep-soak every 2 weeks in summer with good drainage and keep it out of soggy or lawn-adjacent soil.
Like all these sages it should not be sheared into a ball; thin and lightly head back in late winter to preserve its naturally dense rounded form and bloom.
No fertilizer needed for good flowering.
Root rot from excess water is the primary risk; otherwise pest-free.
Evergreen with lush green (not silver) foliage; lavender-purple flowers cover it in repeated flushes from spring through fall after rain, most reliably of the sages.
Soil, Feeding & Propagation
Lean, rocky, sharply drained soils; needs caliche or alkaline pH 7.5-8.5 and rots in clay or lawn soil.
Needs sharp, fast-draining soil.
None — thrives in lean desert soil without fertilizer.
From seed or semi-hardwood cuttings.
4-5 ft
Non-aggressive roots; safe near pools and paving.
Placement Tips
- •A rounded 5 ft shrub; space 4-5 ft apart for a green informal hedge or foundation massing.
- •Its green foliage reads softer and lusher than silver sages, blending into more traditional plantings.
- •Low litter makes it pool-friendly; avoid overwatered turf borders.
- •Full sun and sharp drainage are essential for health and its reliable bloom flushes.
