Rick, Alliaria petiolata is garlic-mustard (as you thought). It has also been known as Alliaria officinalis in recent times, so some books may list it by that name. Here is the "official" list of synonyms from the Flora Novae Angliae web checklist: Name: Alliaria petiolata (Bieb.) Cavara & Grande Synonyms: Alliaria alliaria (L.) Britt.; Alliaria officinalis Andrz. ex Bieb.; Erysimum alliaria L.; Sisymbrium alliaria (L.) Scop.
