A biennial, or occasionally short-lived perennial, herb of dry, usually calcareous soil, occurring in rough pastures, recently cleared woodland, on railway embankments, tracksides and road verges and in quarries and waste places. Seed is copiously produced, and remains viable for many years. It freely hybridises with other Verbascum species. Lowland.
There has been little change in the overall distribution of V. lychnitis, but because it depends on periodic disturbance its abundance can vary markedly from year to year. Large populations can arise where woodland is cleared in forestry operations or as a result of storm damage.
European Temperate element.

Verbascum lychnitis L.
Primarily a plant of waste places and disturbed ground, usually on calcareous soils, V. lychnitis often occurs in large numbers in recently-felled woodland, on railway embankments and on the verges of new roads or tracks. It often grows in association with arable weeds, and with other species of Verbascum with which it freely hybridises.
V. lychnitis is usually regarded as a biennial, but observations on marked plants show that many produce a flower-spike in two successive years. It reproduces by means of its copious seed production. The seeds are able to remain viable for many years when buried in the soil. Felling of woodland and the dragging-out of timber can unearth seeds and cause large colonies to arise on disturbed ground. Such colonies decline again as other, more permanent, vegetation recolonises the area.
V. lychnitis requires periodic soil disturbance for its survival and occasional felling of woodland within its main areas of distribution appears to provide this. The native population increased markedly following the Great Storm of October 1987 and the subsequent clearance of uprooted trees.
Elsewhere in the world, V. lychnitis can be found in France, Holland, Germany, Belgium, Italy, Denmark and Morocco, and is naturalised in parts of Scandinavia and North America.
The British plants are normally white-flowered, but small numbers of yellow-flowered plants occur sporadically around Minehead on the north coast of Somerset, and as casuals or garden escapes in other parts of England, Scotland and Wales.
