Lamium confertum

Lamium confertum, the northern dead-nettle, is a small annual herb of the Lamiaceae family, native to northern and north-western Europe from Ireland and Britain through Scandinavia to northern Russia, and naturalised in Greenland and Iceland. Plants typically grow 10 to 30 cm tall on weak, ascending, square stems that are sparsely hairy and somewhat purplish at the nodes. The opposite leaves are softly green and rounded to broadly ovate or reniform, with shallowly toothed or crenate margins and conspicuous palmate venation; the upper leaves are shortly stalked and often crowded together near the inflorescence, a feature reflected in the specific epithet confertum (meaning crowded). Whorls of small two-lipped flowers are clustered in the upper leaf axils. Each flower has a pink to pinkish-purple corolla about 12 to 18 mm long with a hooded upper lip and a notched lower lip, opening from early spring into summer. Like other dead-nettles the plant lacks any stinging hairs. It grows on arable land, gardens and disturbed waste ground.
