Shoot out of Brussels? (6)

I believe the answer is:

sprout

I believe this clue is a double definition.

'shoot' is the first definition.
(synonyms)

'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.
