Save new receptacle (4)
I believe the answer is:
vase
'receptacle' is the definition.
(I've seen this in another clue)
'save new' is the wordplay.
'new' indicates an anagram.
'save' with letters rearranged gives 'VASE'.
(Other definitions for vase that I've seen before include "Ornamental vessel (for flowers etc)" , "Flower holder" , "Open jar for holding flowers" , "Container for cut flowers" , "Receptacle for flowers - save it" .)
