Flower in waste recycled (5)
I believe the answer is:
aster
'flower' is the definition.
(type of flower)
'in waste recycled' is the wordplay.
'in' indicates a hidden word.
'ASTER' can be found hidden inside 'waste recycled'.
(Other definitions for aster that I've seen before include "Christmas daisy" , "Plant of Michaelmas daisy family" , "bloomer" , "Flower of the daisy family - rates (anag)" , "Stare at pretty flower" .)
