Garlic mustard (Alliaria petiolata) is a highly invasive non-native species that threatens the health of natural communities in areas it infests. The many tiny white flowers give way to elongated slender pods that burst open and scatter dozens of seeds. If you don't pull up that white-flowering plant before it goes to seed this year, be prepared to welcome hundreds more next spring!
