Stoloniferous perennial of the Lamiaceae family, the spotted dead-nettle is native to Europe and Western Asia, where it frequents cool undergrowth, shaded edges, and damp banks on humus-rich soils.
'Shell Pink' forms a dense carpet about fifteen centimeters high. The oval and crenate leaves, velvety to the touch, can appear in two very different aspects: a blade almost entirely silver to whitish, bordered with a simple green edging, or conversely a green background with a well-defined central white spot. In both cases, this light foliage illuminates shaded areas.
The bilabiate flowers, grouped in tight whorls along the upright stems, are a very pale almost pearly pink. In its natural habitat, the species blooms from April to June; in cultivation, an autumn resurgence is possible.
It requires fresh, humus-rich soil, in shade or partial shade, and does not tolerate prolonged summer drought well.
