Beautiful and generally blue-flowered herbs, varying from a few inches to 4 ft. in height, and abundantly scattered in northern and temperate countries. Many kinds are in cultivation. All the medium-sized and large kinds thrive very well in rough places, woods, copses, or shrubberies, among grasses and other herbaceous plants ; while those smaller in size than our own harebell (C. rotundifolia) arc quite at home, and very pretty, on any arid or bare surfaces, such as sandy banks, chalk pits, and even high up on old walls, ruins, etc. In such positions the seeds have only to be scattered. C. rapunculoides and C. lamiifolia do finely in shrubberies or copses, as, indeed, do all the tall-growing kinds. Where there are white varieties they should be secured ; many people will begin to see the great beauty of this family for the first time when they see them growing among the grass or herbs. The effect is far more beautiful than can be obtained in the garden proper.
