The Campanulas are among our most showy perennial or biennial plants; all of them are elegant when in bloom and should be seen more commonly than they are. The stately Campanula pyramidalis, which often grows from eight to ten feet high, forms grand pyramids of blue or white; Campanula Medium (Canterbury bells) is among the best of our border plants, and the dwarf-spreading Campanula carpaticaand its varieties are also very desirable border plants. They delight in a deep rich loam well drained; a mulching of old manure helps to keep the soil cool during the Summer months and to conserve the moisture. The tall-growing kinds should have their flower-stalks supported by neat stakes painted green so as to show as little as possible,
All of the species are easily raised from seeds sown a quarter of an inch deep in early Spring, out of doors or in a frame, and again in the Fall, giving a succession of bloom throughout the year.
