Rose for example worker planted in row (9)
I believe the answer is:
eglantine
'rose' is the definition.
(eglantine is a kind of rose)
'example worker planted in row' is the wordplay.
'example' becomes 'eg'.
'worker' becomes 'ant' (worker is a type of ant).
'planted in' indicates putting letters inside.
'row' becomes 'line' (I've seen this before).
'ant' placed inside 'line' is 'lantine'.
'eg'+'lantine'='EGLANTINE'
'for' is the link.
(Other definitions for eglantine that I've seen before include "Inelegant sort of sweet-brier" , "Wild rose, sweet briar" , "Sweetbriar, inelegant in a way" , "Inelegant (anag.); wild rose" , "Strangely inelegant scented plant" .)
