Cannas are also good for cleaning up any contamination in the soil, be it pesticides, oil slicks, road runoff and more. The plants should then be dug out and thrown away at the end of the growing season to remove the contamination they sucked up.
Several universities (including U Cal) are researching canna's ability to clean up all sorts of pollution.
After a minor (3gal) oil spill at my house a few years ago, I used cannas to suck up the oil that had soaked into the soil. The next year the area was oil free and one of the best growing spots in my yard.
