Canna Lily (Canna indica)

Both Canna edulis and Canna indica are grown for their edible starchy roots. I have grown both, but only the C. indica will flower and produce seed in my climate (zone 5/6). You can also propagate C. indica from stored roots. They can be eaten baked, boiled fried or processed into starch. I tried them baked and found them to be very good. The flavor was not like either a potato or sweet potato, but it was a bit sweet, and the fiberous texture reminded me a bit of spaghetti squash. A dash of salt made them even tastier! I am also finding that Canna roots store over the winter very well with no special conditions required other than cool (50F - 60F), dark and dry.

* The seed will need to be scarified (breaking the hard seed coat) with a file or sandpaper, and then soaked in warm water until they swell. Plant 1/4 inch deep in pots. Set out into the garden as transplants after the threat of frost has passed.
