Trachelium caeruleum, common name blue throatwort, is a species of flowering plant in the family Campanulaceae native to the Mediterranean, where its native range includes Algeria, Morocco, Portugal, Spain, and Sicily. It has also become naturalized in a few areas, including New Zealand, the Azores, and parts of mainland Europe. Growing to 120 cm (47 in) tall by 30 cm (12 in) wide, it is a woody-based erect herbaceous perennial, with oval leaves and dense cushions of violet-purple flowers in summer. The specific epithet caeruleum means 'dark blue'. (Source: Wikipedia.org, CC BY-SA)
