Silver Cloud Texas sage

Leucophyllum candidum. Family Scrophulariaceae. Shrub.

Also called Silver Cloud Texas ranger, Silverleaf Texas sage, Violet silverleaf.

Silver Cloud Texas sage is a compact evergreen shrub grown for its nearly white, woolly foliage and bursts of violet-purple flowers. Usually sold as Leucophyllum candidum 'Silver Cloud', it suits hot, dry gardens with excellent drainage; cold, wet winters are much harder on it than drought.

At a glance

Sun
Full sun, ideally at least 6-8 hours daily; shade reduces flowering and makes growth loose.
Water
Low once established. Water deeply during establishment, then allow the root zone to dry between waterings.
Soil
Sharply drained sandy, gravelly or rocky soil; tolerates alkaline conditions and poor fertility. Avoid heavy, persistently wet soil.
Height
3-5 ft (0.9-1.5 m)
Spread
3-5 ft (0.9-1.5 m)
Flowers
Violet-purple flowers in intermittent flushes from summer into autumn, often following rain or increased humidity.
Foliage
Evergreen. Small, oval leaves densely covered in silvery-white hairs, giving the shrub a bright, almost white appearance.
Growth
Slow to moderate, depending on warmth and growing conditions.
Care needed
Low

Care

Jobs through the year

WaterApr–May, Sep, every 30 days
For established ground plants, water only in prolonged drought when soil is dry; young plants need more.
WaterJun–Aug, every 21 days
Deeply soak established ground plants only during extended drought; let the root zone dry fully.
PruneApr–May
After hard frosts, remove dead tips and lightly shorten stray shoots; avoid bare old wood.
MulchMay
Apply a thin gravel layer, leaving stem bases exposed.
ProtectJan–Apr, Oct–Dec
Not reliably hardy here: grow in a draining pot and overwinter bright and frost-free, sheltered from winter rain.
  • Plant in spring after hard frosts, choosing the sunniest, best-drained position available.
  • Water deeply through the first growing season, letting the soil dry between soakings; reduce watering once established.
  • Avoid routine feeding, especially nitrogen-rich lawn fertiliser, which encourages loose growth.
  • Use a thin gravel mulch and keep it clear of the stem bases.
  • In cool or rainy climates, use a raised bed or a pot with drainage holes and a gritty growing mix; shelter potted plants from prolonged winter rain and hard frost.

Pruning. In late winter or early spring, after the worst frosts, remove dead or damaged stems and lightly shorten wayward shoots. Avoid repeated shearing or severe cuts into old, leafless wood.

Through the year

Late winter
Check for frost damage, but wait until severe frost has passed before removing damaged growth.
Spring
Plant after hard frosts and lightly prune established shrubs if needed.
Late spring
Check that irrigation is not keeping the root zone continuously damp.
Summer
Water young plants deeply when dry; give established shrubs supplementary water only during extended drought.
Autumn
Reduce watering as temperatures fall and clear debris that traps moisture around the crown.
Winter
Keep container plants in a bright, sheltered position and protect them from prolonged freezing and winter wet.

In the garden

  • Repeat along sunny gravel paths to create a low, silver framework without frequent clipping.
  • Combine with agaves and yuccas for contrasting rounded and spiky forms in a dry garden.
  • Plant against dark walls or fences where the pale foliage remains conspicuous between flowering flushes.
  • Use in a large, freely draining courtyard container in regions with unsuitable winter conditions.

Garden styles it suits: Desert modern, Southwestern, Desert / xeriscape, Dry gravel garden, Modern Mediterranean and Low-maintenance.

Plant it with: Red yucca, Whale's tongue agave, Blackfoot daisy, Damianita, Autumn sage and Desert spoon.

Wildlife: Flowers attract bees and other pollinating insects. The dense branching can provide cover for small garden wildlife.

Problems to watch for

  • Root rot in wet soil: improve drainage before planting, reduce irrigation and avoid sites that collect winter water.
  • Frost damage: choose a sheltered position near the cold end of its range and remove dead tips only after hard frosts have passed.
  • Sparse flowering and sprawling growth: move to full sun and stop high-nitrogen feeding.
  • Bare, twiggy plants after repeated shearing: maintain the natural rounded shape with selective, light pruning instead.

Safety

Not known to be toxic to people, cats, dogs or horses. Species-specific safety information is limited, so do not treat the leaves or flowers as edible; despite its common name, it is not culinary sage.

Easily confused with

  • Texas sage (Leucophyllum frutescens)

    Usually has larger leaves and a larger overall habit; its foliage is often grey-green rather than the intensely white, densely woolly foliage of L. candidum. Cultivars can overlap in appearance.

  • Chihuahuan sage (Leucophyllum laevigatum)

    Has narrower, greener leaves, a more open habit and much less conspicuously woolly foliage.

  • Common sage (Salvia officinalis)

    The culinary herb has strongly aromatic, wrinkled leaves and flowers held in upright spikes, rather than individual flowers nestled among white-felted leaves.

The name

Leucophyllum means 'white-leaved' and candidum means 'bright white', both referring to the pale foliage; Texas sage is a common name, not an indication that it belongs to the true sages.

Propagation. Take semi-ripe cuttings in summer and root them in a freely draining medium. Seed-grown plants may vary and will not reliably reproduce the named 'Silver Cloud' selection.
