Beet's close kin (5)
I believe the answer is:
chard
'beet's close kin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for chard that I've seen before include "Vegetable with edible leaves and stalks" , "Variety of beet with edible leaves" , "Type of beet" , "A beet; sounds like burnt" , "Beet with edible leaves and stalks" .)
