Description:

Perennial plant.. The rhizome is short, slanting, forming upright stems and sheds, rooted in the nodes with adventive roots. Stems 15 - 60 cm tall, scarce to thick short fibrous. Leaves with stems,  ovate to round ovoid or lance, 3 - 8 cm long and 2 - 6 cm wide, pointed at the tip, end unevenly serrated, basically cut or slightly heart-shaped; the uppermost inflorescence leaves with short stems or almost seated, ovate or narrowly lance to 3 and 1/2 times longer than broad ones. Blossoms adjacent, gathered 3 to 15 in vertebrae, located in the bosoms of the upper and middle stem leaves. The calyx tubular bell-shaped, 7 - 10 mm long, naked or fibrous, with 5 veins and 5 almost identical triangular teeth, on the top long, strikingly pointed, after blossoming spread out. Corolla 14 - 25 mm long, light to golden yellow with blooming spots, twin; the tube is straight 7 - 10 mm long, over the base slightly pressed, in the upper part expanded, inside with a loosely arranged ring of hairs; upper lip straight, helmet, 10 - 12 mm long, moss with cloves at the end; the lower lip 3-sided with more or less the same shares, the middle one most often triangular, sharp with brown spots. The stamens hidden beneath the upper lip, with yellow, outstretched, bare anthers. Nuts about 3 mm long, back ovate, truncated, on the top flat, black, smooth.

Lamium galeobdolon, commonly known as yellow archangel, artillery plant, or aluminium plant, is a widespread wildflower in Europe, and has been introduced elsewhere as a garden plant. 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.[2]

Description

Yellow archangel is a large-leaved perennial plant with underground runners growing to a height of about 40 to 80 cm (16 to 31 in). 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, 15 to 25 mm (0.6 to 1.0 in) 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.[3]

Taxonomy

There 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] 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.

Distribution

It is native to Europe, and found through Europe and Western Asia.[4]
An introduced species in the USA, Washington State has declared it a "noxious weed" and banned its sale.[5]
