Verbascum nigrum

Verbascum nigrum, the black mullein or dark mullein, is a species of biennial or short-lived perennial herbaceous plant in the mullein genus Verbascum, native to dry open sites in temperate Europe. It grows to 0.5 - 1.5 m.

Verbascum nigrum forms clumps of leaves from which arise multiple tall stems of yellow flowers with purple stamens, blooming over a long period in summer and early autumn. It is cultivated as an ornamental plant, and prefers a calcareous or neutral soil in full sun.
