Lamb's Ear Silver Carpet is a silvery-leaved perennial groundcover prized for its soft, velvety foliage that resembles a lamb's ear. This cultivar is non-flowering or produces minimal blooms, making it ideal for foliage display rather than flower arrangements. It spreads slowly to form dense, attractive mats in rock gardens, borders, and containers.

📏

Spacing: 12 inches

📅

Days to maturity: Establishes within 30-45 days; reaches full mat coverage in 1-2 years

🌱

Planting depth: Plant crowns at soil level; do not bury foliage

Growth Stages

Establishment

2-4 weeks

Young rosettes with silvery leaves emerging; limited spread

Water moderately to help establishment; ensure excellent drainage; keep foliage dry to prevent fungal issues

Vegetative Growth

1-2 growing seasons

Silver-leaved mats expanding outward; plants thickening with dense foliage coverage

Reduce watering as plants mature; deadhead any flower spikes if desired; allow air circulation to prevent rot

Mature Foliage

Ongoing (perennial)

Full carpet of soft, silvery-white leaves; dense groundcover formation established

Minimal water required; maintain excellent drainage; divide if becoming overcrowded; remove any dead or diseased leaves

Dormancy

3-4 months (varies by zone)

Foliage may darken or turn grayish in winter; plants slow growth significantly

Cease fertilizing; ensure soil drains well to prevent winter rot; avoid heavy watering; provide air circulation

Common Pests

Improve air circulation; remove affected foliage; avoid overhead watering; apply sulfur fungicide if severe
Ensure good air circulation; avoid wetting foliage; reduce nitrogen fertilizer; apply neem oil or sulfur in early stages
Increase humidity slightly; spray with water to dislodge; use insecticidal soap if infestation occurs
and
Remove debris where they hide; use copper barriers; hand-pick; apply iron phosphate-based slug bait if needed

Harvest Tips

This is a foliage plant, not typically harvested. For propagation, divide established mats in spring or early fall by cutting sections with roots and replanting; takes 2-3 weeks to establish after division.

Fun Facts

🌱 The common name 'Lamb's Ear' comes from the incredibly soft, fuzzy texture of the leaves, which genuinely feel like a lamb's ear when touched—children are particularly delighted by this tactile quality.
🌱 The 'Silver Carpet' cultivar was specifically selected for its minimal flowering habit and superior foliage color, making it more ornamental than the species form, which produces taller flower spikes.
🌱 Lamb's Ear is native to Turkey and the Caucasus region, and it has been cultivated for centuries in Mediterranean and Alpine gardens for its striking silver-gray coloring, which reflects intense sunlight.
