Florist's inventory (5)
I believe the answer is:
vases
'florist's inventory' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for vases that I've seen before include "Saves in containers for flowers" , "Receptacles for cut flowers" , "Vessels for flowers" , "Containers for cut flowers" , "Open jars for flowers" .)
