Rose, inelegant drunk! (9)
I believe the answer is:
eglantine
'rose' is the definition.
(eglantine is a kind of rose)
'inelegant drunk' is the wordplay.
'drunk' indicates anagramming the letters.
'inelegant' anagrammed gives 'EGLANTINE'.
(Other definitions for eglantine that I've seen before include "Inelegant sort of sweet-brier" , "Inelegant (anag.); wild rose" , "Milton's honeysuckle" , "Sweet brier" , "Strangely inelegant scented plant" .)
