Rose, for instance, gets worker into row (9)
I believe the answer is:
eglantine
'rose' is the definition.
(eglantine is a kind of rose)
'for instance gets worker into row' is the wordplay.
'for instance' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'gets' is a charade indicator (letters next to each other).
'worker' becomes 'ant' (worker is a type of ant).
'into' is an insertion indicator.
'row' becomes 'line' (as in a row of things).
'ant' inserted within 'line' is 'lantine'.
'eg'+'lantine'='EGLANTINE'
(Other definitions for eglantine that I've seen before include "Sweet brier" , "Sweetbriar, inelegant in a way" , "Milton's honeysuckle" , "Rose, growing wild" , "Inelegant sort of sweet-brier" .)
