Lamium galeobdolon

Aluminium Plant

New Zealand Status: Introduced
Conservation Status: Pest Plant

Lamium galeobdolon is a fast growing perennial herb that grows to a height of 400mm to 600mm. The aromatic leaves are ovate to heart-shaped (30-80mm x 35-60mm) with margins coarsely serrated, purplish and hairy on the underside, dark green with large pale silvery-grey patches on the upper surface, and arranged in opposite pars along hairy, square, purplish stems. Lamium galeobdolon produces lemon-yellow flowers (20-25mm long) from Summer to Autumn in dense whorls forming an interrupted spike.

Stems can take root wherever they touch the ground enabling Lamium galeobdolon to rapidly cover large areas of ground with a thick mat that stops other plants from establishing. Due to its invasive habit it is classified as an Unwanted Organism in NZ.

Lamium galeobdolon occurs in disturbed bush, shrubland, and along the margins of water bodies. It is shade tolerant so can grow deep into bush areas. Grows in a wide range of soils from sandy to clay.
