Flower that vanilla comes from (6)

I believe the answer is:

orchid

(Other definitions for orchid that I've seen before include "Expensive, perfumed flower" , "Prized exotic plant" , "Bee, lady, butterfly or slipper -" , "Wild (or much cultivated) flower" , "Exotic flower with strong perfume" .)

I've seen this clue in The New York Times.
