Inelegant wild flower (9)
I believe the answer is:
eglantine
'flower' is the definition.
(thesaurus)
'inelegant wild' is the wordplay.
'wild' indicates an anagram.
'inelegant' is an anagram of 'EGLANTINE'.
(Other definitions for eglantine that I've seen before include "Sweetbriar, inelegant in a way" , "Strangely inelegant scented plant" , "Wild rose, sweet briar" , "Inelegant (anag) - plant" , "Rose, growing wild" .)
