PLEASE HELP: Ive had my spatiphyllum for nearly two years now but it wont flower at the moment. Its leaves are healthy but i dont know why. I was wondering if it was out of season or if i had too many leaves in the pot as it is somewhat overcrowded in there. Im not a gardener, or a plant lover but I want to try and keep one plant alive. They normally dont last long with me. Does anybody know what I can do?

Thanks
Gwyn
