Canna edulis can grow to 3m tall, similar to Canna musifolia grande, it is frost tender so best lifted at the end of the growing season. The small red flowers are produced late August to October given warm conditions and a moist sunny protected spot outside in the UK. The large roots are a source of Canna Starch similar to arrowroot produced by grating the rhizomes but the young sweet fibrous rhizomes can also be eaten although best after many hours of baking.
