Variegated Yellow Archangel – Lamium galeobdolon subsp. argentatum


Also called the ‘Garden Yellow Archangel’, this dead-nettle plant has large, striking yellow flowers. They are two-lipped, with reddish-brown streaks on the lower lip. The hairy leaves are large and paired,  with course, toothed margins, and are almost triangular in shape, splashed with bold silver-grey blotches.

It flowers April to June, and is found in shady woodland, hedgerows, banksides and gardens. A subspecies of the native Lamium galeobdolon, and often found as a garden escapee. Non-native, common and widespread in the south and south-west of Britain, rarer further north. First discovered in the wild in Oxfordshire in 1974, and is now considered an invasive species and a potential threat to native woodland plants in some lowland counties.
