Got up to deliver decorated dish as a prize, maybe (8)
I believe the answer is:
'decorated dish as a prize maybe' is the definition.
(a rosebowl might be given as a prize)
'got up to deliver' is the wordplay.
'got up' becomes 'rose' (past tense of 'raise').
'to deliver' becomes 'bowl' (I've seen this before).
(Another definition for rosebowl that I've seen is " plant in this?".)
