White rose shaped differently (9)
I believe the answer is:
otherwise
'differently' is the definition.
(I've seen this before)
'white rose shaped' is the wordplay.
'shaped' indicates anagramming the letters.
'white'+'rose'='whiterose'
'whiterose' is an anagram of 'OTHERWISE'.
(Other definitions for otherwise that I've seen before include "As an alternative - like white rose" , "White rose (anag.)" , "Under different conditions" , "in different circumstances" , "Apart from that" .)
