Harebell , the common name in this country and England for a beautiful wild perennial plant, campanula rotundifolia. The genus campanula is a large and very ornamental one; the flowers are bell-shaped, as is expressed by the name, which is the diminutive of the Italian campana, a bell. The specific name (round-leafed) was not happily chosen by Linnaeus, as it is only the root leaves which are round; and as these usually decay by the time the plant flowers, the only leaves generally found upon it are those of the stem, which are linear or narrowly lanceolate. The stem is seldom a foot high, often half that, and bears from one to ten small bell-shaped flowers of the most beautiful bright blue color. The harebell is common in Europe and northern Asia, as well as in America, and is most frequent on shaded rocky banks, especially on mountains, which it ascends to great elevations. It is one of the wild flowers frequently alluded to in poetry, and one deserving of more attention from cultivators than it has" received. It will grow in the ordinary soil of the borders, but its most appropriate place is upon the rock-work. There is a double-flowered variety in the French gardens; and an upright, rigid, wild form has been described as a distinct species, C. linifolia.
In England the flowers, treated with alum, are used to make a green dye.
