Lamium maculatum (also known as spotted deadnettle, spotted henbit and purple dragon) is a species of flowering plant in the family Lamiaceae, native throughout Europe and temperate Asia (Lebanon, Syria, Turkey, western China).

Lamium maculatum is a prostrate, spreading herbaceous perennial.[1] This species is very variable in terms of leaf size and shape, hairiness and flower colours. It reaches on average 20–80 centimetres (7.9–31.5 in) in height. It has erect, hollow and pubescent stems, branched at the base only. The soft hairy leaf blades are about 8 inches long. They are spotted (hence the Latin name maculatum), toothed with long petioles, about 2–4 centimetres (0.79–1.57 in) long. Their shape varies from ovate-triangular to heart-shaped. The inflorescence bears about two to eight hermaphrodite flowers about 20–30 millimetres (0.79–1.18 in) long. The flowers of the plant are formed in the leaf axils of the upper leaf pairs. The upper lips of the flowers are helmet-shaped, usually pink or purplish, while the bilobate lower ones are whitish with purple dots. The stamens are located in the upper lip and have orange pollen. The flowering period extends from April through November.
It tends to grow higher in spring while during the colder weather it is much flatter to the ground. If subjected to light frost, L. maculatum will recover in spring as it enters its growth cycle.
It grows in a variety of habitats from open grassland to woodland, generally on moist, fertile soils at an altitude of 0–1,200 metres (0–3,937 ft) above sea level.
L. maculatum is valued as groundcover in moist, shady areas. It will rapidly colonise an area, and may become invasive given suitable growing conditions. Numerous cultivars have been developed, mainly for their coloured and varigated leaves

This plant was found on the river bank of the Rhine river near Zurich, CH. Please provide ID.

It looks rather like Lamium maculatum.

Purpur taubnessel

Thank you … for the ID. Purpur taubnessel is Lamium purpureum as per Wiki.

My immediate thought is that it is Red Dead Nettle (Lamium purpureum), but Henbite (Lamium amplexicaule) also looks pretty similar.

Thank you so much for the feedback.
I found a key at http://michiganflora.net/genus.aspx?id=Lamium which is as follows:
All four species are natives of Europe, two of them known in cultivation and the other two weeds.
1. Corolla ca. 19–26 mm long, the tube curved upward; plants perennial; leaves acute and all petioled.
2. Corolla white, the upper lip ciliate with long hairs (at least 0.5 mm) and usually pilose above as well; terminal tooth of largest cauline leaves prolonged or ± acuminate, often 9 mm or more long.      L. album
2. Corolla pink to purplish [albinos rare], the upper lip with hairs less than 0.5 mm; terminal tooth of largest cauline leaves less than 9 mm long.    L. maculatum
1. Corolla ca. 9–19 mm long, the tube straight; plants annual; leaves acute to rounded in outline, all or only the lower ones petioled.
3. Leaves subtending flowers sessile, ascending or at most horizontal, slightly broader than long (± reniform in overall outline).   L. amplexicaule
3. Leaves subtending flowers short-petioled, reflexed, the blade about as long as broad or a little longer.    L. purpureum
I am not able to nail down the ID of my plant based on this key. Would it be possible to arrive at the correct ID based on my photographs?

Thanks, …, Based on the keys, I will go for Lamium purpureum rather than Lamium amplexicaule if the Corolla is ca. 9–19 mm long

I think … is correct L. puprpureum

Lamium maculatum (L.) L. ??

Yes L. maculatum seems correct ID.

Lamium maculatum ‘Pink Peweter’, ornamental herb cultivated from California

Pewter is because of the silvery greyish white leaf centers, I have had these but never flowered
