Wild rose as a symbol of love (4)
I believe the answer is:
eros
'a symbol of love' is the definition.
(I've seen this in another clue)
'wild rose' is the wordplay.
'wild' indicates an anagram.
'rose' with letters rearranged gives 'EROS'.
'as' is the link.
(Other definitions for eros that I've seen before include "Asteroid - Greek god of love" , "Greek name of Cupid" , "God of love - example of 1 down" , "Piccadilly 14 ac statue" , "Greek love-god" .)
