Verbascum is a genus of over 450 species of flowering plants, common name mullein (/ˈmʌlɪn/[3]), in the figwort family Scrophulariaceae.

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.

The leaves are spirally arranged, often densely hairy, though glabrous (hairless) in some species.

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.
