Canna lilies were a vital food source for Northwestern Native Americans and contain the highest percentage of starch of any known tuber. They can be cooked like potatoes though the natives would also make flour from them. To obtain canna lily flour slice the tubers into 1/4" disks and allow them to dry for a day or two. Then crumble these disks up in a large bowl of water. The starch (flour) will sink to the bottom of the bowl and any fiber will float to the top where it can be collected and discarded. Allow the starch to dry completely then grind/pound it into flour.

The young shoots can be cooked and eaten like asparagus and the leaves can be used like banana leaves to wrap food for baking.

These plants are hardy and grow very well in most conditions though they prefer sun and moisture. Leaf-roller caterpillars will "stitch" the top growing leaves together resulting in stunted, ugly growth but they don't kill the plant. Just open up the leaves and remove the caterpillar. You can also cut the rolled leaves off and the plant will resume normal growth.
