Follow woman to get a flower (3,4)
I believe the answer is:
dog rose
'a flower' is the definition.
(I have seen 'Hedgerow flower ' mean 'dog rose' so perhaps 'flower' could also mean 'dog rose')
'follow woman' is the wordplay.
'follow' becomes 'dog' (dog can mean to follow or torment).
'woman' becomes 'rose' ().
'dog'+'rose'='DOG-ROSE'
'to get' acts as a link.
(Other definitions for dog rose that I've seen before include "bloomer" , "something smelling nice in the hedgerow" , "Flower of the hedgerow" , "wild shrub" , "Hedgerow plant" .)
