Botanical Name

STACHYS byzantina

Plant Common Name

Lamb's Ear, Wooly Betony

General Description

This easy, heat tolerant, mat-forming perennial is one of the best silver plants for the garden. Lamb’s ear originates from the Caucasus Mountains and the rocky hills of Iran. It is primarily grown for its broad, oval, wooly leaves that are silver to gray in color. In early to midsummer silvery spikes covered with pink flowers are produced, which are very attractive to bees. Old flower spikes should be removed to keep plants looking well groomed.

This perennial prefers a hot full sun and thrives in average to poor, well drained soil. Plants tend to spread vigorously and should be divided every two to three years. Grow lamb’s ear in mixed perennial borders, rock gardens or along the top of stone retaining walls.
