Fall-blooming plant (5)
I believe the answer is:
aster
'fall-blooming plant' 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 "Tears (anag) - plant" , "Christmas daisy" , "Flower of the daisy family - rates (anag)" , "Stare at pretty flower" , "(Starlike) flower" .)
