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.[2] It has also become naturalized in a few areas, including New Zealand, the Azores, and parts of mainland Europe.[2]
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.[3] The specific epithet caeruleum means "dark blue".[4]
In temperate climates this plant is usually grown as a half-hardy annual for summer bedding schemes or planters. It has gained the Royal Horticultural Society's Award of Garden Merit.[5] There are many cultivars with a variety of flower colors, including white, red, pink, and dark purple.[6]
