Lamb's Ear 'Silver Carpet' is a low-growing, non-flowering ornamental cultivar prized for its soft, silvery-white fuzzy foliage that forms dense ground cover mats.

Growth Stages

Establishment

2-4 weeks

Young plants develop initial silvery rosettes and begin spreading horizontally. Foliage is soft and velvety but plant is still small.

Water regularly to establish deep roots. Mulch lightly around plants but keep away from crowns. Reduce watering frequency after 2-3 weeks as roots develop.

Vegetative Growth

4-8 weeks

Plant spreads laterally, filling in the designated space with dense silvery mat. Leaves remain fuzzy and soft-textured with minimal vertical growth.

Minimal supplemental watering needed once established. Remove any weeds competing for space. Deadhead rare flowering spikes if they appear to maintain foliage focus.

Mature Ground Cover

Ongoing spring-fall

Fully established dense mat forming complete ground cover, typically 4-6 inches tall with abundant fuzzy silvery foliage. Very few or no flower spikes visible (non-flowering cultivar).

Maintain by removing dead or damaged leaves in spring. Cut back by one-third if plant becomes leggy or sparse. Avoid overhead watering to prevent fungal issues in humid climates.

Dormancy

3-4 months (winter)

Plant slows growth in winter; foliage may look dull or slightly grayed. In mild climates, remains semi-evergreen; in cold zones, foliage dies back.

Stop watering in cold climates; reduce frequency in mild areas. Do not fertilize. Remove dead foliage in early spring once danger of hard frost passes.

Harvest Tips

Lamb's Ear 'Silver Carpet' is primarily grown for foliage texture rather than harvest. Cut stems for fresh or dried arrangements by snipping 4-6 inch segments as desired. For dried arrangements, cut in mid-summer when foliage is most fuzzy and silvery; bundle and hang upside down in a warm, dry location for 1-2 weeks. Cut back entire plant by one-third to one-half in early spring to rejuvenate growth and maintain compact form.

Fun Facts

🌱 The common name 'Lamb's Ear' refers to the fuzzy texture of the leaves, which genuinely feel as soft as a lamb's ear—making it a popular plant for children's gardens and sensory landscapes.
🌱 'Silver Carpet' is a nearly sterile cultivar specifically selected to be non-flowering, distinguishing it from the species which produces tall purple flower spikes; this breeding ensures the plant's energy goes entirely into beautiful foliage production.
🌱 The fuzzy silver coating on the leaves (called tomentum) serves as a natural adaptation: it reflects intense sunlight and reduces water loss, making the plant extremely drought-tolerant and ideal for xeriscaping projects.
