Fall bloomer (5)
I believe the answer is:
aster
'fall bloomer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aster that I've seen before include "Plant like a Michaelmas daisy" , "Stare at pretty flower" , "Showy garden flower" , "Tears about bright flower" , "It grows" .)
