Mullein or "mullein leaf" often refers to the leaves of Verbascum thapsus, the great or common mullein, which is frequently used in herbal medicine.

Verbascum are biennial or perennial plants, rarely annuals or subshrubs, growing to 0.5 to 3.0 m (1.6 to 9.8 ft) tall. The plants first form a dense rosette of leaves at ground level, subsequently sending up a tall flowering stem. Biennial plants form the rosette the first year and the stem the following season. The leaves are spirally arranged, often densely hairy, though glabrous (hairless) in some species. The flowers have five symmetrical petals; petal colours in different species include yellow (most common), orange, red-brown, purple, blue, or white. The fruit is a capsule containing numerous minute seeds.

In gardening and landscaping, the mulleins are valued for their tall narrow stature and for flowering over a long period of time, even in dry soils.
