Symphytum officinale, commonly known as comfrey, boneset, or knitbone, is a large, bulbous, thick, tufted perennial (up to 3′ tall and 2.5′ wide). It is now mainly cultivated as an ornamental plant for its foliage and attractive spring flowers.
The large, hairy, pointed, oval-lance-shaped, deep green basal leaves grow up to 8″ long. Upper leaves are deciduous and smaller than basal leaves.
