Let us know if they come back. I live in NE OH as well and the cold is what convinced me not to try Zantedeschia when I moved up here. I'm going to try some in containers this year...

Hi,
I received a potted Calla Lily as a gift last week and would like to plant it outside, do you know if I can plant it outside now, it has long flowered stalks. I live in North Carolina and the weather is starting to get warm , spring like. I appreciate any advise, thank you.....

Kathy.....I am in nc and my callas come back. I have then planted close to the foundation of my house, I don't know if that has any bearing. last year was the first year they came back. they were humungous! last forever as a cut flower in the house. I love them. bought more last year and planted in a different spot. have not seen a sign of then yet. I will post pictures of the blooms.....

I am not going to hijack this thread, I just wanted to say that calla lilies will overwinter just fine in my part of Ohio inside. I just left them in the soil and put them in a cool dark place and forrgot about them. I started rewatering them and put them under my flourescent lamp and the first leaf popped up and now another one is coming up. Sorry kind of blurry but you can see the second leaf popping up!
