Tea rose (5)
I believe the answer is:
china
I believe this clue is a double definition.
'tea' is the first definition.
(I've seen this before)
'rose' is the second definition.
(China rose is an example)
(Other definitions for china that I've seen before include "friend or companion" , "High-quality porcelain" , "chum" , "Far Eastern power" , "communist state" .)
