About

Aconitum lycoctonum (wolf's-bane or northern wolf's-bane) is a species of flowering plant in the genus Aconitum, of the family Ranunculaceae, native to much of Europe and northern Asia. It is found in lowlands to the subalpine zone, mainly in forests and shaded habitats. Along with A. napellus, A. lycoctonum is of the most common European species of the Aconitum genus. They are also grown ornamentally in gardens, thriving well in ordinary garden soil. As such, A. lycoctonum can be found in North America, especially in eastern Canada, often in old gardens or as garden escapees.

Lycoctonum is a rendering in modern Latin of the traditional name "wolf's-bane". Aconitum lycoctonum's name was given by Carl Linnaeus, who found A. lycotonum growing in Lapland, Finland in 1727.
