I have bunches from Chris's co-op can these be grown as house plants or do they need a rest period????
caladiums
They need a rest period. When temps start to get in the low 50's bring them inside and let them go dry and dormant. If you have them in pots, stop watering, trim back foliage and store the pots in a warm place. If they're in ground treat them as you would a canna or similar bulb. Trim foliage back, dig up and dry for a day or two and then store them in peatmoss in boxes or bags. Hope that helps!
Should I wait for the foliage to die back naturally or should I just dig them up and cut it off?
frost warnings 2night gere in MICH!!!! mine are getting covered! NO TIME
I usually let my cannas get frost nipped before I dig them and bring them in; Is this ok for caladiums? They're so beautiful now I hate to cut all thost big leaves off and dig them, but now I'm wondering if that should be a weekend project. Thanks, Neal.
I've heard that they can't take frost. I think there's a post in tropicals called winter aroid care that explains it.

Cannas can grow fine in zone 7 or 8 which gets frosts. So, they're hardier. Caladiums are rated as zones 9 or 10, which are relatively frost free. They're not used to it and won't take it too well.
