The campanulas are a big family, some biennials, as the Canterbury bell, the rest perennials, the bell flowers, varying from 3—6 in. in the alpine varieties. The taller border plants are blue, white or purple, run to 4 ft. and are among those perennials that can be planted with safety right up to the end of April, with care as to watering. Canterbury bells are hardy biennials and will flower in May and June. They flower — dark and light blues and white — earliest in sunny positions. A rather light, well manured, limy soil suits the campanulas. The root does not expand very quickly and so 1 ft. will be enough to allow each way for development for a couple of seasons. These tall kinds bear the flowers on upright stems that do not need to be staked. A dwarf variety, attica, has violet flowers and there are many more desirable forms for rock gardens. The trailing pot or hanging basket types are grown from seed sown in heat in March. Division in spring is the best means of increasing nearly all Campanulas. There is a very attractive pink variety C. lactiflora Loddon Anna which grows to about 41/2 ft. C. rotundijolia (blue) is the blue bell of Scottish gardens.
