By crossing and selection the florists have made remarkable advances with the canna within recent years, in shortening the growth and improving the flowers in size and beauty. Some of the French, Italian, and Crozy varieties of the present are a wonderful advance on the "Indian shot" of a few years ago. Like the tulip, after a start of the best varieties has been secured, they may be retained with moderate care for many years. On large lawns quite extended circular beds, with castor-bean plants in the centre and an edging of upright vinca, give a fine effect. Against a background of green the richly colored flowers show well. They are also used for centre-pieces for flower-beds, and also in small groups on borders and in shrubbery group borders. As the flowers begin to fade they should be clipped, to prevent the development of seed, which is not favorable for continued blooming. In the fall, when the tops are withered by the first frosts, but prior to a freeze that will kill the crowns of the root-stalks, dig the roots and dry them partially, when they can be kept on a shelf in a furnace-heated cellar, not too close to the heater. We have kept the root-stalks in entire hills on the cellar-bottom in a furnace-dried cellar-room, but they are apt to start growth in such position if not divided and potted by the first of February. The dividing is very easy, as the root-stalks are separated almost as distinctly as the tubers of the common potato. (See Fig. 32.)
