Shrub wife put in ground by grassy area (11)
I believe the answer is:
wintergreen
'shrub' is the definition.
(wintergreen is a kind of shrub)
'wife put in ground by grassy area' is the wordplay.
'wife' becomes 'w'.
'put in ground' becomes 'inter' (I've seen this in other clues).
'by' is a charade indicator (letters next to each other).
'grassy area' becomes 'green' (I've seen this before).
'w'+'inter'+'green'='WINTERGREEN'
(Other definitions for wintergreen that I've seen before include "Medicinal plant oil" , "shrub" , "for which golfers head around Christmas?" .)
