Echium pininana, also called tree echium, pine echium and giant viper's-bugloss, is a plant, native to La Palma in the Canary Islands, that is now cultivated in gardens of Britain and Ireland. Its native habitat is laurel forests, where it is now endangered through habitat loss. E. pininana is a biennial or triennial, showing little more than leaf in the first year, but subsequently produces a dense, 4 metres (13 ft) high (potentially) flower spike that carries a dense mass of leaves and small blue flowers.
