Yellow archangel: Lamium galeobdolon
Most species of the evergreen Lamium genus, a member of the Labiatae family, can be found in Europe, north Africa and Asia. This dead nettle is a rhizomatous herbaceous perennial that spreads rapidly by means of runners, thus forming a dense carpet of leaves up to 30 cm (12 in) high. In summer it produces whorls of tubular yellow flowers, flecked with brown, measuring 2 cm (nearly 1 in) across. ‘Florentinum’ has silver-marked leaves that turn reddish in autumn. Less aggressively invasive are ‘Hermann’s Pride’ with silvery-green leaves and ‘Silver Angel’ with a creeping habit. Spreading can be controlled by pruning at the beginning of spring. The plant can also be divided. If planted near other plants make sure that the latter do not get suffocated by the spreading deadnettle. These excellentgrow best in moist in partial shade.
