Parts of a flower (6)
I believe the answer is:
petals
'parts of a flower' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for petals that I've seen before include "Palest parts of flowers" , "Parts of flowers in pastel" , "Flower parts on plates" , "1 across (anag)" , "Outer parts of flowers" .)
