Inelegant sort of climber (9)
I believe the answer is:
eglantine
'climber' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'inelegant sort' is the wordplay.
'sort' is an anagram indicator.
'inelegant' is an anagram of 'EGLANTINE'.
'of' is the link.
Can you help me to learn more?
(Other definitions for eglantine that I've seen before include "Inelegant sort of sweet-brier" , "Strangely inelegant scented plant" , "Milton's honeysuckle" , "Wild rose, sweet briar" , "Sweet brier" .)
