I am a transplant from ct via fl to nc, zone 7. I have never grown callas before because you had to dig them up and store them for the winter.....no way jose! now that I am in nc, zone 7, I planted my first callas two years ago. when they came up the second year or should I say first year after planting, they blew me away! they were humungus, huge, big,large, tall and oh so beautiful. I picked a few and placed them on my counter in the kitchen to enjoy. they lasted so long in the vase that I had to finally throw them in my compost. what a wonderful lily. I planted lots more last year and am patiently waiting for them to show their stuff!! happy gardening.
