Canna (Indian Shot or Hemp).
For pot-plants on terraces, gravel walks, and such like places, few things can equal and none surpass Cannas. They are half-hardy perennials, and may be increased from seed or by dividing the roots late in autumn, allowing them first to partially dry. File the tough skin off one end of the seed, and steep it in hot water for a few hours before it is sown, then stand it in a hot place till it has germinated. Harden off and plant out, or shift into larger pots in June, using a rich, light soil. Lift and store the roots in autumn in the same way as Dahlias. Different kinds flower at various seasons, so that a succession of bloom may be had throughout the year. Height, 2 ft. to 10 ft.
