(Brassica oleracea var. gemmifera)
Brassicaceae
family
Brussels sprouts are closely-related to cabbages (which is why they look like mini-cabbages), broccoli, cauliflower, collards or kale, and kohlrabi. This vegetable probably originated as a mutation in wild or primitive Mediterranean cabbages, and was first noted under cultivation in the Belgian city of Brussels. The edible portion of the plant is the floral buds, which grow axially along the stem. It is a popular vegetable in northern Europe and the U.S.
