I really like the look of Calla Lilies in a garden, but haven't found a variety that is hardy in my zone (7). Is there anything I can do to successfully overwinter them? Is it possible to dig them up and carry them inside to put in pots when the weather cools down?

I think a lot of members do just that. they might keep them in pots year round to make it easier.

That may be the easiest thing to do.

I live in what you would class as zone 4/5 and this winter has been the coldest on record so it is a challenge to try save more tender plants, well tender to us here in UK, I lift my Canna's soon as flowering passes say about October, shake most soil off the tubers I also like to shake the tubers in a bag with powdered Captan or better still powdered Flowers of sulphur, both are bought from the pharmacist, this stops any rot off the tubers in storage, I do this with my Dahlias also, but you have to keep an eye out for rot anyway and cut these bits off, once the tubers have settled into the pots, about 2/3 weeks, thats when I cut the stems and foliage off to about 6 inches above the soil level, store them in a cold greenhouse, if freezing temps come, I put on my heater for several hours at night, they usually start to show new growth round about May-June when I can plant them outside again, over here in UK, Canna's are late flowerers unless started into flower still in the greenhouse, they like a handful of bone-meal added to the planting hole /soil. hope this helps. good luck. WeeNel.
