In the past month I've planted several varieties of elephant ears in containers. The labels indicate that at least some of them are perennials, perhaps hardy to zone 8. What should I do with them come fall? Bring them inside? If so, what conditions do they need? I overwinter some tender plants in my basement, which has windows but not bright light; we keep a light on a timer during the day, although I'm not sure how much it helps. Should I add light? Should I remove the bulbs and store them when the foliage dies? Leave them outdoors in their containers? Does it make a difference if the containers are plastic or pottery? If I can keep them alive, I'd like to do that rather than replacing them.
