Mullein verbascum thapsus identification
Description
They are biennial or perennial plants, rarely annuals or subshrubs, growing to 0.5 to 3 metres (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.
Cultivation
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. Many cultivars are available, of which 'Gainsborough','Letitia' and 'Pink Domino' have gained the Royal Horticultural Society's Award of Garden Merit.
Since the year 2000, a number of new hybrid cultivars have come out that have increased flower size, shorter heights, and a tendency to be longer-lived plants. A number have new colors for this genus. Many mulleins are raised from seed, including both the short-lived perennial and biennial types.
Other uses
The plant has a long history of use as a herbal remedy. Although this plant is a recent arrival to North America, Native Americans used the ground seeds of this plant as a paralytic fish poison due to their high levels of rotenone. Verbascum flowers have been used in traditional Austrian medicine internally (as tea) or externally (as ointment, tea, baths or compresses) for treatment of disorders of the respiratory tract, skin, veins, gastrointestinal tract, and the locomotor system.
The plant's stem is considered a first-rate drill for use in the hand drill method of friction fire lighting.
