I am not in any way green fingered however I was given the lily as a present in Jan 2010. It had several flowers and continued to flower until the summer that yr. Since then it has not flowered at all. I have repotted it from a 8" to a 10" pot (about 1 yr ago). I have tried it in every room in the house and the last 6 months it has spent in the bathroom, under a frost glass window which I was told would be ideal. The plant itself looks amazing, loads of very shiny leaves and keeps growing, however no sign of any flowers at all. What am I doing wrong????
