Verbascum pulverulentum, the hoary mullein,[2] is a species of flowering plant in the family Scrophulariaceae.

[1][4] It is a specialist on coastal shingle, and so is preadapted to human-influenced habitats such as old quarries and gravel pits, road verges, railway embankments, and similar disturbed stony ground.

[5] It is a stout biennial or monocarpic perennial herb growing up to 1.5 m tall, producing flowers and seeds only once, during its second or a later year.

The stems and leaves are densely woolly with pale grey to glaucous pubescence.

[6] It is the main food plant for the moth Nothris verbascella (Norfolk snout).
