Exotic plant (6)
I believe the answer is:
orchid
'exotic plant' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for orchid that I've seen before include "Exotic and expensive flower" , "Family of flowers with unusual shapes and beautiful colours" , "Chord I play for the flower" , "Ornate flower" , "Prized exotic plant" .)
