Wild rose in elegant setting (9)
I believe the answer is:
eglantine
'wild rose' is the definition.
(I've seen this before)
'in elegant setting' is the wordplay.
'setting' indicates an anagram.
'in'+'elegant'='inelegant'
'inelegant' anagrammed gives 'EGLANTINE'.
(Other definitions for eglantine that I've seen before include "Strangely inelegant scented plant" , "Inelegant (anag) - plant" , "Milton's honeysuckle" , "Rose, growing wild" , "Sweetbriar, inelegant in a way" .)
