Comfrey is a cultivated perennial herb. The plant grows up to 1 metre tall. Its leaves add relatively high amounts of nitrogen, potassium and phosphorus to the compost pile. It has lance-shaped, hairy leaves, hairy stems and magenta-pink flowers. The tubular pink flowers are in bud, turning mauve or blue and blooms from May to August. The plant can be harvested for both leaves and tubers. Comfrey has been used for thousands of years as a medicinal herb. The plant is now often grown specifically for its great usefulness as a fertiliser.
