Yellow Archangel - Lamium galeobdolon
Lamiastrum means "resembling Lamium", referring to the similar-looking deadnettles that are also grown as ornamental ground covers.
The flowers are soft yellow with a prominent "hood" (the dorsal lobe of the corolla). It spreads easily and so has been commonly used as an ornamental ground cover. It can be invasive in places where it is not native and caution must be taken when planting in these areas.
This Eurasian native is an introduced species in the United States. Washington State has declared it a "noxious weed" and banned its sale. A garden escapee, Yellow Archangel has the potential to spread into natural areas in Wisconsin, although is not considered invasive here and is not proposed for regulation at this time.
Other Names: artillery plant, aluminium plant, or yellow weasel-snout.
