Canna lily is an amazing plant that has long captured the fancy of gardeners the world over. A native of the Americas, it boasts beautiful varieties of flowers as well as one of the highest starch contents of any plant; it is actually cultivated for food in many places.
An avid water-lover, wild Canna is usually found in soft, well drained soils along sunny streams and slow moving rivers. It is the often extensive root system which is of culinary value. Having a flavor and texture similar to water chestnuts, the sliced roots may either be eaten raw or cooked in a variety of dishes. As with most roots, the best time to gather these is after the first frost and before the advent of Spring.
If you’d like to plant these wonderful plants on your property, they enjoy looser, sandy to silty well-drained soils in open sunlight. They can endure moderate flooding, but would suffer from prolonged inundation. The best method for transplant is to cut a section of root during the Winter and re-plant in a suitable spot.
