Allium vineale is also expected to be found in Wisconsin and Texas; specimens were not seen. It is a noxious weed, apparently introduced from Europe in colonial times. The small, wheat-sized bulbils frequently contaminated wheat grown in infested areas. Bread made from such wheat was garlic-flavored, and cows grazing in infested pastures produce garlic-flavored milk. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
