Vegetable shoot (6)
I believe the answer is:
sprout
This clue is a double definition.
'vegetable' is the first definition.
(I know that sprout is a type of Leaf vegetable)
'shoot' is the second definition.
(I know this)
(Other definitions for sprout that I've seen before include "Bud; a type of cabbage" , "Spring up like vegetable from Brussels" , "Start growing" , "Produce buds" , "Put out shoots for a brassica" .)
