'Alba Augusta' Looks like a form of S. nicholai, which I have never seen flower without growing at least 3 m tall.

thanks your your reply at the moment nearly 2 meters tall but as out grown conservatory the biggest left nearly touching the roof the picture in question was taken before i bought the plant in vale-exotics.co.uk

and it's in a 60 litre pot

i really want it to flower badly been feeding it lots to help it to flower i wish the consecratory was much taller
