About
Lycopus europaeus, common names gypsywort, gipsywort, bugleweed, European bugleweed and water horehound, is a perennial plant in the genus Lycopus, native to Europe and Asia, and naturalized elsewhere. Another species, Lycopus americanus has also been erroneously called L. europaeus.
Where it grows
Gypsywort grows primarily in wetland areas. It grows along the borders of lakes, ponds and streams as well as in canals and marshes. Its carpels float which may aid dispersal of the plant and its rhizomeous roots also allow the plant to spread. It is in flower from June to September, and produces seeds from August to October.
