Two weeks ago, I purchased a calla lily rhizome and I planted it immediately. I know it should be planted in fall for indoors but my book said to plant it in spring for outdoors. It is still indoors because the temperature is still too cold to bring it outside. It has now been 2 weeks since I planted the rhizome and still no sign of growth. A friend of mine told me calla lily grows pretty fast. I was wondering how long before I see shoots? Could something be wrong with the rhizome I purchased? It seemed healthy. Thanx to anyone who can help me. Helga
