Lamb's ear is an herbaceous perennial that is native to Turkey and the Southern Caucasus Mountain region. Plants grow about 1 foot tall. It is grown for its texture and color of foliage. Leaves are densely covered with gray or silver-white wooly hairs. Lamb's ear was given its name because of the curved shape of the leaves and the soft, white, fur-like hair that covers them. It can thrive in poor soil, but cannot take excess water. In some areas, lamb's ear is considered invasive because it is hard to control.
