Can you help name this white bell flower

Thank you in advance cheers ..poppy

 

I reckon that is a Narcissus of some sort.

 

Got it now thank you its a Narcissus 'Thalia' :-D

 

Beat me to it, I was coming back to say that, had to go and check the label in the garden and then it was too late.

 

Nice daff. Haven't seen this kind around here. We got lots of yellows...
