Winner's wreath (6)
I believe the answer is:
laurel
'winner's wreath' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for laurel that I've seen before include "Sweet bay tree" , "girl" , "Foliage used in making wreaths" , "Leaf of the wreath of honour" , "Hardy's chum" .)
