Saves wrecking vessels (5)

I believe the answer is:

vases

I'm a little stuck... Click here to teach me more about this clue!

'vessels' is the definition.
(I know this)

'saves wrecking' is the wordplay.
'saves' anagrams to 'VASES'.
But, I'm not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for vases that I've seen before include "Open jars for flowers" , "Receptacles for cut flowers" , "Saves in containers for flowers" , "Pots for cut flowers" , "Vessels for flowers" .)

I've seen this clue in the Evening Standard.
