BLUEBELL, the name applied in England to the wild hya cinth (Scilla festalis) and in Scotland and the United States and Canada to the harebell (Campanula rotundifolia), in both cases on account of the shape of the flowers. In the eastern United States the Greek valerian (Polemonium reptans) is also called bluebell; on the Pacific coast Phacelia minor, a plant of the water leaf family (Hydrophyllaceae), is known as the California blue bell. (See CAMPANULA ; HYACINTH ; VIRGINIA COWSLIP.)
