Edible stalks; traditional hubbub (7)
I believe the answer is:
rhubarb
(Other definitions for rhubarb that I've seen before include "Plant with thick stalks that are cooked in desserts" , "Garden plants with fleshy stalks or slang nonsense" , "Nonsense; plant with edible leaf stalks" , "Stalks edible when cooked" , "Low-level racket" .)
