Bean plant (7,6)
I believe the answer is:
scarlet runner
'bean plant' is the definition.
(scarlet runner is a kind of bean plant)
This is the entire clue.
(Other definitions for scarlet runner that I've seen before include "Variety of bean" , "trained climber in garden" , "one to train on the pole in garden" , "one going up the pole" , "Flushed athlete" .)
