Natural history / Folklore

Gives smell to cow’s milk when eaten as forage. Alien plant that is taking over native plant habitat, and through competition removing key sources of native butterfly food - especially the toothworts. Over 30 species prey on it in its native Europe, none are in North America as a result it hits densities here unseen in Europe. Garlic flavor prevents foraging by white-tailed deer and most other native herbivores which has aided its take over of habitat.6
