This upright perennial features bristly, unbranched, four-angled stems lined with deeply wrinkled, coarsely toothed leaves that closely resemble true stinging nettles, though they completely lack stinging hairs. It produces stunning clusters of large, nodding, bell-shaped flowers. These striking blossoms are typically a rich violet-blue or occasionally a delicate white, with hairy interiors.
Interesting Facts
Its traditional name “Throatwort” stems from the ancient Doctrine of Signatures; because the throat-shaped flowers resemble the human larynx, it was widely brewed into medicinal gargles to treat sore throats and swollen tonsils. Unlike actual stinging nettles, the leaves are entirely gentle to touch. Historically, the young, tender spring leaves and roots were consumed raw in wild salads.
Importance to Wildlife
An absolute sanctuary for specialized biodiversity, its large bells function as a crucial refuge and high-value nectar source. It is heavily dependent on long-tongued bumblebees and solitary bees. Crucially, it serves as the essential pollen source for the rare, specialised Campanula Blunthorn Bee (Chelostoma campanularum) and provides larval food for the beautiful, declining Pug moth species.
Advice
The plant is non-toxic; indeed rabbits and deer will sometimes eat it so it can be difficult to find.
