Revolted after scoundrel does for flower (3,4)
I believe the answer is:
dog rose
'flower' is the definition.
(I have seen 'Hedgerow flower ' mean 'dog rose' so perhaps 'flower' could also mean 'dog rose')
'revolted after scoundrel' is the wordplay.
'revolted' becomes 'rose' (I've seen this before).
'after' says to put letters next to each other.
'scoundrel' becomes 'dog' (dog is a kind of scoundrel).
'rose' put after 'dog' is 'DOG-ROSE'.
'does for' is the link.
(Other definitions for dog rose that I've seen before include "bloomer" , "Flower of the hedgerow" , "something smelling nice in the hedgerow" , "Hedgerow plant" , "wild shrub" .)
