I know I've seen them before but can't remember what they are. Some sort of lily perhaps?? ???

Whatever it is - it's beautiful!!....sorry I can't help altho it looks familiar :)
It looks very much like Curcuma alismatifolia- a member of the ginger family, commonly known as Siam Tulip.
Just looked it up and you're spot on Deeds!!! Thank you. ;D
I have seen these sold in nurseries for exorbitant fees as 'flowerer's of the moment'
One thing I was told was never buy them off the street sellers cos they hate draft!! Is this so?
