It grows in damp woodland, beside roads and paths,
in limestone pavement grikes, hedgerows,relic
gardens and brownfield sites.
Yellow Archangel is a native, stoloniferous herb
growing up to 30cm and forming extensive patches.
The stolons are thick and root easily, thereby spreading
the patch.
The hooded flowers are yellow and the 'tongues' have
red honeyguides.
The stamens are hidden in the hood.
Leaves are dark green and shaped like stinging nettle
leaves.
The naturalised garden escapes, Lamiastrum galeobdolon
subsp. argentatum, are common and have white marks
on the leaves.
It has spread rapidly in the last 30 years and was
pronounced an invasive alien in 2013.
