Edible Bud/Origin

Origin
The Brussels sprout is a cultivar in the Gemmifera group of cabbages (Brassica oleracea), grown for its edible buds. The leafy green vegetables are typically 2.5–4 cm (0.98–1.6 in) in diameter and look like miniature cabbages. The Brussels sprout has long been popular in Brussels, Belgium, and may have originated there.
