I've never grown any. My dad has them all around his screened in back porch. I don't recall him ever talking about having trouble with leaf rollers. I don't think he does much to his canna though. Just plants and digs them each year. I need to start getting some from him. Seeds and the bulbs but he only has red. They are pretty but I would like to have some of the other colors also...I don't need another flower obsession
that's for sure.
