Plant in the middle of Kent facing direction of sunrise (7)
I believe the answer is:
eastern
'facing direction of sunrise' is the definition.
(the sun rises in the east)
'plant in the middle of kent' is the wordplay.
'plant' becomes 'aster' (aster is a kind of plant).
'in' means one lot of letters goes inside another.
'the middle of' means to look at the middle letters.
The central letters of 'kent' are 'en'.
'aster' put into 'en' is 'EASTERN'.
(Other definitions for eastern that I've seen before include "Could be Chinese" , "Chinese', for example" , "from afar" , "Nearest (anag) - oriental" , "China?" .)
