Water and transplant bergenias (6,3)
I believe the answer is:
bering sea
'water' is the definition.
(Bering Sea is an example)
'transplant bergenias' is the wordplay.
'transplant' indicates anagramming the letters.
'bergenias' anagrammed gives 'BERING SEA'.
'and' acts as a link.
(Other definitions for bering sea that I've seen before include "lot of cold water" , "Water between Russia and Alaska" , "Northern waters" , "Part of the North Pacific between Alaska and Siberia" , "cold waters" .)
