Urns (5)
I believe the answer is:
vases
'urns' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for vases that I've seen before include "Open jars for flowers" , "Jars for flowers (5)" , "Receptacles for cut flowers" , "Saves in containers for flowers" , "Pots for cut flowers" .)
