White Rose represented in a different way (9)
I believe the answer is:
otherwise
'a different way' is the definition.
(I've seen this before)
'white rose represented' is the wordplay.
'represented' indicates anagramming the letters.
'white'+'rose'='whiterose'
'whiterose' anagrammed gives 'OTHERWISE'.
'in' is the link.
(Other definitions for otherwise that I've seen before include "Differently - or else!" , "in different circumstances" , "White rose (anag.)" , "Under different conditions" , "As an alternative - like white rose" .)
