Lamb's ears are grown for its thick, suede-like, silver-gray leaves which typically form a rapidly spreading mat approximately 4-6" tall. Runners spread the dense, woolly, gray green leaves that have a tongue shape. Leaf shape and texture resemble a lamb's ear, hence the common name. Semi-evergreen leaves will depreciate considerably in harsh winters and will burn if they are in too much sun. Small-leaved flowering stems with spikes of insignificant, purplish-pink flowers appear in summer rising above the foliage 10-15" tall. Many gardeners will remove the flowering stems to promote a denser ground cover effect.
