Common comfrey is a hairy plant of damp ground and is found beside rivers, in fens and ditches, and on roadside verges and waste ground. It often grows in clumps and displays clusters of bell-shaped, pinky-purple flowers from May to July. It has become an important plant for organic gardeners as its roots reach deep into the soil making it rich in minerals, while its leaves can be used for slug control, as a fertiliser and as a composting aid.
