 They are named lamb's ears because of the leaves' curved shape and white, soft, fur-like hair coating.Flowering stems are erect, often branched, and tend to be 4-angled, growing 40–80 cm tall.The leaves are thick and somewhat wrinkled, densely covered on both sides with gray-silver colored, silky-lanate hairs; the undersides are more silver-white in color than the top surfaces.
