Bush country (7)
I believe the answer is:
america
'country' is the definition.
(United States of America)
'bush' is the wordplay.
I cannot really understand how this works, but
'bush' could be 'erica' (erica is a kind of bush) and 'erica' is located in the answer.
The remaining letters 'am' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for america that I've seen before include "Western land mass" , "West Side Story song" , "Continent consisting of two great land masses" , "Country bordering Mexico" , "'Country named after Vespucci, Italian navigator (7)'" .)
