Help with calla lilly care?

Yes you can keep them in the house. When the leaves die, cut them off at the soil level, water occasionally, and in early spring fertilize them. They will leaf out and flower again next spring/early summer.

My husband bought me two calla lily plants this year i have never kept them before but they seem to take care of themselves. They flowered after we had purchased them and as the flowers died i cut them off. Within a week or two there were more flowers and they are still in bloom. I have them planted out in the garden next to the pond and they obviously dont mind all the rain we are having.

Yes, you can keep them in the house and they should flowere again next year.
