Sends up flowers: did settle up front (9)
I believe the answer is:
satirises
'sends up' is the definition.
(I've seen this before)
'flowers did settle up front' is the wordplay.
'flowers' becomes 'irises' (type of flower).
'did settle' becomes 'sat' (sat or settled down).
'up front' means one lot of letters go next to another.
'irises' after 'sat' is 'SATIRISES'.
(Other definitions for satirises that I've seen before include "Makes fun of" , "Makes exaggerated attacks" , "Ridicules" , "Sends up" .)
