common mullein

Common mullein, scientifically known as Verbascum thapsus, is a species within the genus Verbascum. These plants are typically biennial or perennial herbs native to temperate regions, particularly Eurasia. The common mullein can grow between 0.6 to 2 meters (2 to 7 feet) tall and features a single, unbranched stem with large, velvety leaves. Its pale-yellow flowers are about 2.5 cm (1 inch) in diameter and grow in a dense spike at the top of the plant.1

Mulleins are often considered weeds in pastures and are commonly found in disturbed areas and along roadsides, though they have also been used in gardens. The flowers of various mullein species can range in color from white to blue, purple, and red. The term "common mullein" is also used interchangeably with "great mullein".12
