Trachelium caeruleum
Also called Blue Throatwort
Throatwort (Trachelium caeruleum) is a woody-based perennial from the Mediterranean, usually grown as a half-hardy annual for summer bedding and containers in cool climates. It needs full sun and free-draining soil, and it is best treated as a short-lived plant in temperate gardens.
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".
