Potpourri pouch (6)
I believe the answer is:
sachet
'potpourri pouch' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sachet that I've seen before include "Little sealed packet" , "Small bag - chaste (anag)" , "Scent bag - shampoo envelope" , "'Small soft bag, for perfumed powder say (6)'" , "Package" .)
