Attractive drooping clusters of blue, purple, pink or cream, bell-shaped flowers in early summer above mounds of mid-green leaves. Comfrey is excellent groundcover for a moist, partially shady border or woodland edge. Although a good companion for ferns and shade-loving woodland plants it's best sited away from smaller, less vigorous species. The leaves can be steeped in water to make 'comfrey tea', which produces an excellent organic plant food.
