It displays the zygomorphic flower morphology, opposite leaves, and square stems typical of the mint family, Lamiaceae. The flowers are soft yellow and borne in axial clusters, 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.[3] DescriptionYellow archangel is a large-leaved perennial plant with underground runners growing to a height of about {{convert|40|to|80|cm|0|abbr=on}}. The paired opposite leaves are stalked, broadly ovate with a cordate base and toothed margin. The underside of the leaves is often purplish. The flowers grow in whorls in a terminal spike. The calyx is five-lobed. The corolla is yellow, {{convert|15|to|25|mm|1|abbr=on}} long, the petals fused with a long tube and two lips. The upper lip is hooded and the lower lip has three similar-sized lobes with the central one being triangular and often streaked with orange. There are two short stamens and two long ones. The carpels are fused and the fruit is a four-chambered schizocarp.[4] TaxonomyThere are a number of closely related taxa which hybridize with L. galeobdolon and in some cases are not unequivocally accepted as distinct species but considered subspecies or varieties by many authors.{{citation needed|date=November 2011}} Most well-known among these is variegated yellow archangel (subsp. argentatum), whose leaves often have variegation, showing as silver patches arranged as a wide semicircle. This, and in particular its large-flowered and even stronger-marked cultivar 'Variegatum', is the taxon most often met with as a garden escapee. DistributionIt is native to Europe, and found through Europe and Western Asia.[5] An introduced species in the USA, Washington State has declared it a "noxious weed" and banned its sale.[6] Subspecies
