Cut flower for the platform (4)
I believe the answer is:
dais
'platform' is the definition.
(dais is a kind of platform)
I can't explain the rest 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" , "stand" , "stepping up here?" , "Speaker's raised platform" , "Throne platform" .)
