An evergreen dwarf shrub growing to 1 m (3.3 ft) tall and broad, it is noted for the pronounced silver woolly hairs on its leaves, whence the Latin specific epithet lanata.

[3] The deep violet purple flowers are borne on narrow spikes, and give off the familiar lavender scent.

Lavandula lanata is cultivated in temperate zones for its attractive appearance and fragrance.

[4] It is hardy in mild and coastal areas, tolerating temperatures down to about −5 °C (23 °F), but preferring a warm, sheltered location in full sun.

It has gained the Royal Horticultural Society's Award of Garden Merit.
