Lamb's Ears

Lamb's ears is highly drought-tolerant once established, requiring only occasional deep watering during prolonged dry spells. Avoid overhead watering and wetting the foliage to prevent rot, as the fuzzy leaves trap moisture easily. Reduce watering significantly in winter to prevent soggy root conditions.

Thrives in full sun, requiring at least 6 hours of direct sunlight daily to maintain its compact growth habit and vibrant silver foliage color. It can tolerate light partial shade, particularly in hot, arid climates, but excessive shade will cause leggy growth and reduce leaf fuzziness. Too much shade also increases the risk of fungal disease.

Prefers well-drained, sandy or loamy soil with a neutral to slightly alkaline pH, and tolerates poor, low-nutrient soils exceptionally well. Heavy clay soils that retain moisture will cause rapid root rot, so amend heavy planting sites with sand or gravel to improve drainage before planting. Avoid rich, overly fertile soils, as they promote overly lush, weak growth.

Requires very little fertilization, as excess nutrients cause leggy, floppy growth and reduce the plant's signature silver foliage color. An annual light topdressing of compost in early spring is sufficient for most garden-grown plants. Avoid synthetic, high-nitrogen fertilizers entirely, as they can damage the plant's root system and reduce drought tolerance.

Hardy in USDA zones 4 through 8, tolerating winter temperatures as low as -30°F (-34°C) when planted in well-drained soil. It thrives in warm, dry summer conditions, but struggles in regions with high summer humidity and frequent rain. In areas with hot, humid summers, provide extra airflow and ensure perfect drainage to prevent foliage rot.

Remove spent flower spikes as they fade if you wish to prioritize foliage growth, as blooming redirects energy away from leaf production. In early spring, trim back any brown, damaged, or rotted leaves from the previous winter to encourage fresh, new foliage growth. If the plant becomes leggy or overgrown in mid-summer, shear it back by one-third to promote a compact, dense habit.

Easily propagated by division in early spring or early fall, simply dig up mature clumps, separate them into smaller sections with intact roots, and replant immediately in well-drained soil. It can also be grown from seed sown directly outdoors after the last frost date, though seed-grown plants may have slightly variable foliage texture and color. Softwood cuttings taken in late spring also root readily in well-drained potting mix with consistent light moisture.

Prefers low to moderate humidity levels, and struggles in high-humidity environments where moisture becomes trapped on its fuzzy foliage. In humid climates, space plants 12-18 inches apart to promote good air circulation around the leaves, reducing the risk of fungal disease. Avoid misting or spraying the foliage directly, as this can cause leaf spotting and rot.

If grown in containers, repot every 2-3 years in early spring, using a fast-draining succulent or cactus potting mix to prevent excess moisture retention. Choose a pot with ample drainage holes, and avoid overpotting, as excess soil will hold unnecessary moisture around the roots. When repotting, gently divide overgrown clumps to keep the plant compact and prevent overcrowding.
