Bifid Hemp-nettle

Galeopsis bifida is an annual plant native to Europe and Asia but now found in Canada and the northeastern, midwestern parts of the United States. It has many common names such as bifid hemp-nettle, split-lip hemp-nettle, common hemp-nettle, and large-flowered hemp-nettle. The genus name means weasel-like, referring to the corolla of the flower. It is often confused with other species of Lamiaceae such as Mentha arvensis, Dracocephalum parviflorum and Stachys pilosa.
