Red-faced state is never-ending (6)
I believe the answer is:
florid
'red-faced' is the definition.
(I've seen this before)
'state is never-ending' is the wordplay.
'state' becomes 'florida' (US state).
'is never ending' means to remove the last letter.
'florida' with its final letter taken away is 'FLORID'.
(Other definitions for florid that I've seen before include "Excessively ornamented" , "Ruddy, flushed" , "(Of language) flowery" , "Excessively ornate" , "Flushed and flowery" .)
