Cotton Lavender is a genus of small shrubs and sub-shrubs, grown for their foliage and yellow or white button flowers. The leaves are aromatic and usually silver.
There are up to 18 species, native to the Mediterranean, especially Spain, where they grow on cliffs and dry slopes.
They do best in full sun and very well-drained soil. They are drought tolerant, but hate winter wet. In very cold areas some winter protection may be required. Hard pruning after flowering prevents excess woody growth.
