S. lanata), the lamb's-ear[2] (lamb's ear)[3] or woolly hedgenettle,[4] is a species of flowering plant in the mint family Lamiaceae, native to Armenia, Iran, and Turkey.

Lamb's-ear flowers in late spring and early summer; plants produce tall spike-like stems with a few reduced leaves.

The leaves produced on the flowering stems are greatly reduced in size and subsessile, the lower ones slightly longer than the interscholastic and the upper ones shorter than the verticillasters.

The corollas have some darker purple tinted veins inside; they are 1.2 cm long with silky-lanate hairs but bases that are glabrous.

[7][8] Lamb's-ear is a commonly grown plant for children's gardens, as it is easy to grow and the thick felt-like leaves are fun to touch.

In Brazil it is used as an edible herb, called peixinho-da-horta prepared battered and deep-fried sprinkled with lemon juice and said to taste fish-like.

[11] Due to its relatively high rate of evapotranspiration, Stachys byzantina is a potentially useful species for rainwater retention and therefore flood prevention.
