One of the easiest grown foliage plants is the canna; of course it will flower, but primarily when grown in the window garden it is a foliage plant. The best one to grow is Black Beauty. Outdoors, this canna grows five to six feet high but grown in a pot reaches only two or three feet in height. The leaves are rich, glistening, bronzy purple, shaded black and the margins of the leaves are crimped and wavy. The flowers are small but may not appear in house culture.
The bulbs can be bought from seed suppliers, but an easier way is to dig up the bulbs which have flowered in the garden during the summer. Dry them off and then pot them up in six or seven-inch pots and start them growing. The plant will make a good show all winter and may be put outdoors in the flower bed again in the summer.
