Country, in the morning, with heather (7)
I believe the answer is:
america
'country' is the definition.
(United States of America)
'morning with heather' is the wordplay.
'morning' becomes 'am' (as in 12:00 AM).
'with' is a charade indicator (letters next to each other).
'heather' becomes 'erica' (the plant genus Erica includes heather plants).
'am'+'erica'='AMERICA'
'in the' acts as a link.
(Other definitions for america that I've seen before include "Take care and aim for the continent" , "'Country named after Vespucci, Italian navigator (7)'" , "Curious camera I take to the continent" , "The superpower" , "North or South, it's a continent" .)
