Brussels sprouts originated from wild cabbage plants native to the Mediterranean region, but the vegetable as known today was developed and popularized around Brussels in Belgium during the Middle Ages. That Belgian connection is why they are called “Brussels” sprouts, not “brussel” sprouts.

Deep roots in the Mediterranean

  • Brussels sprouts descend from a wild cabbage-like species that originally grew along the Mediterranean coast.
  • Ancient Romans are believed to have cultivated early forms of these sprout-like cabbages, long before the modern variety appeared.

How Belgium made them “Brussels”

  • By around the 5th century, improved cabbage types had spread north into cooler parts of Europe, setting the stage for the sprout’s evolution.
  • In what is now Belgium, farmers refined these plants into the familiar tall stalks studded with many small “mini-cabbages,” with commercial cultivation established near Brussels by the 13th century.

When the name stuck

  • The vegetable gained wide popularity in the Brussels region by the 16th–18th centuries, and that strong local association led to the name “Brussels sprouts.”
  • English and other European sources consistently refer to them in the plural and with the final “s,” reflecting their link to the city of Brussels itself.
