Court impounding cheapo plastic vase from France (8)
I believe the answer is:
cachepot
'vase from france' is the definition.
(French term for a kind of pot)
'court impounding cheapo plastic' is the wordplay.
'court' becomes 'ct'.
'impounding' indicates putting letters inside.
'plastic' indicates an anagram (plastic can mean easily moulded).
'cheapo' is an anagram of 'achepo'.
'ct' placed around 'achepo' is 'CACHEPOT'.
(Other definitions for cachepot that I've seen before include "Flower holder" , "ornamental cover" .)
