Cut flower for stage (4)
I believe the answer is:
dais
'stage' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for dais that I've seen before include "Said to be a low platform" , "Welshman's" , "Platform, rostrum" , "Said (anag.)" , "Speaker's raised platform" .)
