Fall bloomers (6)
I believe the answer is:
asters
'fall bloomers' 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 oddly at the flowers" , "Christmas daisies" , "Stares around at the flowers" , "Daisylike flowers" , "Stares at bright flowers" .)
