I have planted calla lilies this year. I planted them in march. I read that they should be planted in fall for indoor and spring for outdoors. I will be using mine as indoor plants and was wondering if it was OK to have planted them in spring. This will make for an inversion of the growing/dormant period. Will this matter? When is the real dormant period for calla? My callas are growing fine now but wil they flower? Should I have kept the rhizomes for planting in fall? Did I do the right thing in planting them now? If some of you are familiar with callas as houseplants your help would be nice. Helga
