Lamb’s ears is well loved for its densely hairy leaves. Keeping those fuzzy leaves dry is important for the health and beauty of this plant. These plants are strong growers and have the potential to spread aggressively.
Size and Method of spreading:
Lamb’s ears is a low-growing to mounded ground cover, growing 12 to 15 inches high. It takes on a more upright appearance as the flower stalks develop. It is a colonizing ground cover. Colonizing ground covers produce underground stems that spread out horizontally and shallowly, produce roots, and then send up new shoots. These plants are strong growers and may have the potential to grow aggressively.
Native geographic location and habitat:
This plant is native to Turkey and Iran.
Leaves mainly grow from the base of the plant and are oblong to elliptic. They are densely hairy, giving the plant a gray-green to whitish appearance and a soft, felt-like feel.
Small, purple-pink flowers are borne on upright stalks and grow up to 6 inches tall. Flowering time is from summer into frost, but the flowers are not very showy.
Fruit are small nutlets and not ornamentally important.
It is important for this plant to have well drained soil. Overhead watering can be a problem as well, since the hairy leaves can trap water, leading to rot.
List of pests, diseases, and tolerances:
Rot and leaf diseases can be a problem when conditions are too wet. Slugs can also be a problem, but it is resistant to deer and tolerant of black walnut toxicity.
