Plants in container put in this place (7)
I believe the answer is:
herbage
'plants' is the definition.
(herb plants)
'container put in this place' is the wordplay.
'container' becomes 'bag' (bag is a kind of container).
'put in' is an insertion indicator.
'this place' becomes 'here' (here in this location).
'bag' put inside 'here' is 'HERBAGE'.
'in' acts as a link.
(Other definitions for herbage that I've seen before include "Plant life" , "Vegetation" .)
