Lamium galeobdolon

Lamium galeobdolon, the yellow archangel, is a species of flowering plant in the mint family Lamiaceae. It is native to Europe and western Asia but it is widely introduced in North America and elsewhere. It is the only species in the genus Lamium with yellow flowers. Another common name for this species is golden dead-nettle. In New Zealand, it is called the aluminium plant or artillery plant. The common names archangel and dead-nettle have been in use for hundreds of years, dating back to at least the 16th century. Lamium galeobdolon comprises four closely related subspecies that are sometimes considered to be four separate species, one of which, the variegated yellow archangel (Lamium galeobdolon subsp. argentatum) from central Europe, is widely present as an invasive subspecies in several European countries outside of its native range and also in New Zealand, Canada, and the United States....read more on Wikipedia.
