I just bought a calla lily plant at Walmart and the plant marker said it is a perenial for zone 4-8. Is this true, new hybrid? anyone heard of it?
I don't kow what you might have but I've only heard of Callas successfully overwintering zone 6 and up and in zone 6 they had a bit of help (mulching)
I have to dig mine up every winter and store indoors. Its a big job but well worth the effort.
No, it is very doubtful. The white Zantedeschia Aethiopica is the hardiest and it is rated zone 7 and up.
Here is a link that might be useful: callas
that what i thought too but bought it anyway to see if it will survive this coming winter in zone6. thanks both for responding.
