Carrot's kin (5)
I believe the answer is:
anise
'carrot's kin' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anise that I've seen before include "Aromatic Mediterranean plant" , "Plant with seeds used as flavouring" , "Plant with aromatic seeds" , "Herb with aromatic seeds" , "Plant giving ouzo flavour" .)
