Fall flowers (6)
I believe the answer is:
asters
'fall flowers' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for asters that I've seen before include "Stares at bright flowers" , "Stares around at the flowers" , "Daisylike flowers" , "Stares oddly at the flowers" , "Christmas daisies" .)
