Echium
Echium /ˈɛkiəm/[1] is a genus of approximately 70 species and several subspecies of flowering plant in the family Boraginaceae.
Species of Echium are native to North Africa, mainland Europe to Central Asia, and the Macaronesian islands where the genus reaches its maximum diversity. 29 species of Echium are endemic to the Canary, Madeira, and Cape Verde archipelagos.[2] The continental species are herbaceous, whereas all but two of the endemic species of the Macaronesian islands are woody perennial shrubs.[3]
The Latin genus name echium comes from the Greek ἔχιον echion referring to Echium plantagineum[4] and itself deriving from ἔχις echis "viper"; the Greek term dates to Dioscorides who noted a resemblance between the shape of the nutlets to a viper’s head.[5] The genus Echium was published by Carl Linnaeus in 1753.
Many species are used as ornamental and garden plants and may be found in suitable climates throughout the world.
In Crete Echium italicum is called pateroi (πάτεροι) or voidoglosses (βοϊδόγλωσσες) and its tender shoots are eaten boiled or steamed.[6]
Echium species are used as food plants by the larvae of some Lepidoptera species including Coleophora onosmella and orange swift.
