Flower from Cumberland Gap in Kentucky (4)
I believe the answer is:
pink
'flower' is the definition.
(pink is a kind of flower)
'from cumberland gap in kentucky' is the wordplay.
'from' indicates a hidden word.
'PINK' is hidden in the letters of 'cumberland gap in kentucky'.
(Other definitions for pink that I've seen before include "Colour it's healthy to be in" , "Knock (of engine) - garden flower" , "(Shade of) flower" , "Miscoloured beast supposedly seen in delirium" , "sportsman's coat" .)
