Bloom revolted mate (7)
I believe the answer is:
rosebud
'bloom' is the definition.
(I know that rosebud is a type of bud)
'revolted mate' is the wordplay.
'revolted' becomes 'rose' (I've seen this before).
'mate' becomes 'bud' (short for buddy).
'rose'+'bud'='ROSEBUD'
(Other definitions for rosebud that I've seen before include "Young flower (to be gathered?)" , "Immature rambler" , "Young flower (gathering recommended!)" , "one with potential to bloom" , "Partially-opened flower" .)
