Bearded bloomer (4)
I believe the answer is:
iris
'bearded bloomer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for iris that I've seen before include "Coloured part of the lamp" , "Part of the eye, usually brown or blue" , "Flag - part of eye" , "plant with showy flowers" , "pupil's governor" .)
