| Bird's-eye view. [Yet again, another place, another time, it is caught sharing a bed with Stinging Nettle and Cleavers lurk on the left]. |

| An escaped garden flower similar to White Dead-Nettle but with mauve-coloured flowers and spotted leaves. |

| The flowers whorled and the whorls are tiered. Leaves in opposite pairs on a square stem, the leaves alternating in quadrature up the stem. [It doesn't grow this high, your Author is suspending it in mid-air for a better view] |

| Flowers in shades of pink and white. Leaves roundly-toothed (crenate). The stems appear to be telescoped at each flower whorl, and therefore get thinner up the stem in jumps. Hairs on stem angled ~45° downwards. The whorls of flowers are directly above a pairs of leaves near the summit and emerge from widening beetroot-coloured sepal tubes with long teeth. The flowers have a large hood at the top in which lies four stamens and a single style which lays close to the back of the flower emerging from deep down inside and is concolorous with the hood making it hard to see. There are two side-wings and from between those a long 'tongue' grows which has two 'flippers' splayed out. Five 'petals' in all. |

| Flowers are in two parts, a large hood and two lower lobes usually rolled underneath. |

| The 4 anthers are brown and in 2 pairs. The stigma emerges between them, poking a little way downwards. The petals are covered in short white hairs. |

| Four (white at the moment) fruits developing within each sepal tube. Your Author knows not what the beetroot-coloured blotches on the leaves are, Spotted Dead-nettle does not normally exhibit these. |

| The sepal tubes have 5 sepal teeth. Another identifying feature are the sepal teeth on each side of the lower part of the sepal tube. |

| The lower lobes have white markings whilst the upper hood has just a white rim. Leaves are usually spotted white, as here. |

| But the leaves may instead have a central ragged silvery blotch down the centre. Leaves irregularly double-toothed. |

| Yet other leaves may have the white spots and the central blotch down the centre. It is possible the beetroot-red stains on some leaves are an extension of the beetroot-red staining of the sepal teeth and leaf stalk. |

| Leaf double-toothed and with shorter hairs than the main flower stem. Almost looks as though vandals have painted the leaves with silver paint. |
