Brussels sprout

Brussels sprouts—the variety of cabbage with a stout stem and a budlike head of tightly folded leaves—are named after the city of Brussels. The modern version of the plant was originally grown primarily in the area of Northern Europe now known as Belgium, of which Brussels is the capital. In the name of the cabbage, Brussels is usually capitalized like the name of the city, though some publications don’t capitalize it.

The Wikipedia page doesn't even say "Brussel sprout" is an error. It avoids the term entirely.

    In that city, they don't have the same name for it that we do, they call it "wheat lettuce" (or "wheat salad").

      ? They just call it spruiten, so "sprouts". And the French speakers call it "cabbage from Brussels"

        Okay I just checked and "salade de blé" is something else. My memory mixed them up.
