Overview
Lamb’s Ear is widely grown as a groundcover and border plant due to its distinctive woolly foliage. It performs best in dry, sunny locations and is commonly used in rock gardens and xeriscape plantings. The plant is also valued in sensory gardens for its soft leaf texture.
Lamb’s Ear care is generally simple when plants are grown in fast-draining soil and are not overwatered.
Plant Description
Lamb’s Ear forms low rosettes of thick, velvety leaves that spread gradually by short runners. Plants develop a dense carpet of foliage over time, helping suppress weeds and stabilize soil.
Growth is moderate and steady under warm, sunny conditions.
Flower Description
In late spring to early summer, upright flower spikes emerge above the foliage. Small purple to pink flowers appear along the stems.
Some gardeners remove flower spikes to maintain a compact foliage display.
Foliage Description
Leaves are thick, soft, and covered in silvery hairs that give the plant its characteristic appearance. The foliage remains attractive throughout most of the growing season.
In mild climates, leaves may persist into winter.
Deciduous or Evergreen
Herbaceous perennial. Semi-evergreen in warm regions.
USDA Grow Zones
Zones 4–9.
Mature Height and Width
6–12 inches tall (foliage)
12–18 inches tall in bloom
12–24 inches wide
Growth Habit
Spreading, mat-forming perennial.
Native Range
Native to the Middle East including Turkey, Armenia, and Iran.
Sun Exposure
Full sun promotes compact growth and dense foliage. Plants tolerate light shade but may become loose or prone to disease in low light.
Soil Requirements
Lamb’s Ear growing conditions require very well-drained soil. Sandy, rocky, or gravelly soils are ideal.
Avoid heavy clay or areas that remain wet.
Water Requirements
Provide moderate watering during establishment. Once established, Lamb’s Ear tolerates drought and requires infrequent watering.
Overwatering is a common cause of plant decline.
Fertilizing
Minimal fertilization is needed. Excess nutrients may encourage weak, floppy growth.
Pruning and Maintenance
Remove spent flower stems to improve appearance. Trim damaged or aging foliage to maintain plant vigor.
Divide clumps every few years to prevent overcrowding.
Pests and Problems
Generally resistant to pests and deer. Crown rot may occur in humid climates or poorly drained soil.

Heat Tolerance
Performs well in dry summer heat when soil drainage is adequate.
Cold Tolerance
Very cold hardy within recommended zones.
Landscape Uses
Suitable for groundcover, edging, rock gardens, xeriscapes, and mass plantings. The plant provides year-round texture and contrast against green foliage plants.
