Symbol of freshness (5)
I believe the answer is:
daisy
'symbol of freshness' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for daisy that I've seen before include "Common plant" , "Lawn flower, weed" , "See 1 Across" , "chain, just the smallest bit?" , "Grassland flower" .)
