Teucrium is a genus of perennial plants, of the family Lamiaceae. Common names for this genus include germanders. These species are herbs, shrubs or subshrubs. They are most common in Mediterranean climates.
Several are used as food plants by the larvae of some Lepidoptera species including the Coleophora case-bearers Coleophora auricella and Coleophora chamaedriella. The latter is only known from Wall Germander.
