Lamb's ear is the common name for *Stachys byzantina*, a perennial herb in the mint family. It is grown mainly as an ornamental for its soft, silver-gray foliage and is native to parts of Turkey, Iran, and the Caucasus region. In Canada, it is a common ornamental perennial in dry, sunny borders and rock gardens due to its drought tolerance and hardiness.

Description

Lamb's ear is known for its thick, fuzzy leaves covered in hairs called trichomes. These leaves are usually the main ornamental feature, while the small clustered flowers are secondary in garden use. The flowers are pink to purple, sometimes white, and are borne on upright spikes. Some cultivars flower sparsely.

Cultivation and care

The plant prefers average to dry, very well-drained soil and full sun to partial shade. It is drought tolerant, but excess moisture and high humidity can cause crown rot and leaf disease. It is typically hardy in USDA zones 4 to 9.

Uses in gardens

Lamb's ear is commonly planted as a low-maintenance ground cover, border edging, or in children's and rock gardens. Its soft texture and silvery colour make it popular in decorative landscapes. In Canada, it is commonly used in dry, sunny borders and rock gardens.

Taxonomy and native range

The species belongs to the mint family and is native to rocky areas of Turkey, the Caucasus, and Iran. The genus name *Stachys* is derived from Greek, and the species name *byzantina* means 'of Byzantine'.

Key facts
