Droop, as a flower (4)
I believe the answer is:
wilt
'droop as a flower' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wilt that I've seen before include "Ave --; black --" , "Lose strength and become limp" , "Become flaccid" , "fade" , "tire?" .)
