Yellow archangel is an introduced European shade and sun tolerant forest-edge species of mint (Lamiaceae) that is now naturalized in North America. It is commonly used as a ground cover and in hanging baskets. It is reported from five US states (CA, MA, NY, PA, VA) (USDA 2010). In Canada, it is reported from British Columbia, where it is recognized as a naturalized urban invasive in the Greater Vancouver area. It has become established in natural areas, parks and ravines. It is also reported from campsites in the Skagit River Valley. It is a shade-loving species that establishes primarily from garden waste, but also by simple spread from gardens. It does particularly well in part-shade in moist soils. It is persistent once it is established and can form thick, continuous ground covers. This is an easily recognized species that spreads by creeping stems. It has opposite, usually variegated, leaves and square stems typical of the mint family of plants.
