Shoot out of Brussels? (6)

I believe the answer is:

sprout

This clue is a double definition.

'shoot' is the first definition.
('sprout' can be a synonym of 'shoot')

'brussels?' is the second definition.
(I've seen this before)

'out of' is the link.

(Other definitions for sprout that I've seen before include "Put out shoots for a brassica" , "Grow during stupor" , "Produce buds" , "Start to grow" , "Young shoot" .)

I've seen this clue in the Evening Standard.
