Flowery violet (6)
I believe the answer is:
purple
I believe this clue is a double definition.
'flowery' is the first definition.
(both can describe elaborate prose)
'violet' is the second definition.
(I know that violet can be written as purple)
(Other definitions for purple that I've seen before include "Colour of the angry" , "Colour between 14dn and blue" , "Red and blue mix" , "Mixture of red and blue" , "Colour associated with imperial authority" .)
