Revolted - could be a bloomer (4)
I believe the answer is:
rose
I believe this clue is a double definition.
'revolted' is the first definition.
(I've seen this before)
'a bloomer' is the second definition.
(I know that rose is a bloomer)
'could be' acts as a link.
(Other definitions for rose that I've seen before include "Gained height" , "Wine colour; plant" , "Thorny flowering plant" , "beauty" , "came up" .)
