Wild eglantine not cultivated (9)
I believe the answer is:
inelegant
'not cultivated' is the definition.
(I've seen this before)
'wild eglantine' is the wordplay.
'wild' indicates an anagram.
'eglantine' with letters rearranged gives 'INELEGANT'.
(Other definitions for inelegant that I've seen before include "Unpolished" , "Awkward - graceless" , "Ungraceful" , "stiff" , "laboured" .)
