Bean-bearing tree (5)
I believe the answer is:
cacao
'bean-bearing tree' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cacao that I've seen before include "Bean providing chocolate" , "Tropical tree, the source of chocolate" , "Tree with seeds used to make chocolate" , "Tree for cocoa bean" , "Tree from which chocolate is made" .)
