Plant one of many used in café (6,4)
I believe the answer is:
french bean
'plant' is the definition.
(French bean is an example)
'one of many used in cafe' is the wordplay.
I cannot really see how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is present in the answer.
'many' could be 'c' (C is the Roman numeral for 100) and 'c' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for french bean that I've seen before include "Green vegetable" , "Haricot vert" .)
