Floral decoration (7)
I believe the answer is:
rosette
'floral decoration' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rosette that I've seen before include "To steer (anag)" , "Ribbon badge for prize-winner" , "Mark of affiliation" , "Equestrian prize" , "Arrangement of ribbons presented as a prize" .)
