You give tips on growing calla lilies. But I could find no mention of "how long" it takes to grow calla lilies inside and bloom. Does it take 6 weeks? I have a friend who wants to do this for a wedding.

There is really no way to predict the exact timing of Calla Lily flowering.
The bulbs generally began producing flowers when the plants mature.
Plants can be started in January for blooms to start from May to the end of the summer.
