'Lily'..................!!

This is a plant that my Mam was given for her 90th birthday,
I think it's a Calla Lily??.....it didn't do very well outside last year....it did come back but there were no flowers on it.....
So, this year I decided to put it in the greenhouse and look at it now...
It's flying...still only one flower but growing really well....!
I suppose I'm trying to say.......I'm really so thrilled to own a glasshouse at last!!
