Plant found in bedpan is edible! (5)
I believe the answer is:
anise
'plant' is the definition.
(anise is a kind of plant)
'in bedpan is edible' is the wordplay.
'in' says the answer is hidden in the clue.
'ANISE' is hidden within 'bedpan is edible'.
'found' acts as a link.
(Other definitions for anise that I've seen before include "Aromatic Mediterranean plant" , "Herb with aromatic seeds" , "Plant giving ouzo flavour" , "Plant with seeds used as flavouring" , "Plant providing flavour similar to liquorice" .)
