God of the roses (4)
I believe the answer is:
eros
'god' is the definition.
(I know that Eros is Greek deity)
'of the roses' is the wordplay.
'of' says the answer is hidden in the clue.
'EROS' can be found hidden inside 'the roses'.
(Other definitions for eros that I've seen before include "Roman god of love, Cupid" , "Goddess" , "God of love; life instinct (Freud)" , "Greek god of love - see statue in Piccadilly" , "Form of love" .)
