Often where you find this plant you also find the large caterpillars of The Mullein moth.
Insight into Great Mullein (Verbascum thapsus): a biennial, this native verbascum grows to over 2 metres in height. It is covered with soft, whitish, woolly hairs which make the leaves appear particularly unappetising but clearly The Mullein (Shargacucullia verbasci) moth caterpillars disagree as it is one of their foodplants.
