Calla lilly mystery
Bought one last year at a local nursery and planted next to my small pond. Dug up the bulb for the winter and returned it outside when it had sprouted, sometime in May. Well, there are four tall, healthy looking leaves, but there has never been even the slightest indication of a flower. Can anyone give me an explanation for this? Won't bother digging it up this year if it won't flower from now on.
