Yellow Archangel is a widespread herbaceous perennial wildflower in the UK and Europe growing to about 30-45cm (1-1.5ft) high in dense patches in shady conditions. Some cultivars of Yellow Archangel (EG "Variegata") are widely planted as a ground cover garden plant which can be become quite invasive as their stems aggressively root where they touch the earth.
It displays a zygomorphic flower morphology with opposite leaves and a square stem typical of the mint family. It has soft yellow flowers in axial clusters with a prominent "hood" similar to that of other Lamiums.
It is capable of hybridization with other Lamium species and a well known among these is the variegated Yellow Archangel - Lamium galeobdolon variegatum, whose variegated leaves show as silver patches in a wide semicircle. This is the Yellow Archangel plant most often seen in the wild as a garden escapee, as shown by our photos on the right as found in Brickfields Park.
