Edible bulb (5)
I believe the answer is:
onion
'edible bulb' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for onion that I've seen before include "reason for tears" , "veggie" , "Tear-jerking bulb" , "associated with 26 [TRIPE] ?" , "Aromatic flavourful versatile vegetable" .)
