Most of the plants we condemn as weeds are not native to America.
More than a thousand kinds were introduced here, intentionally or
unintentionally, from foreign lands. We intend to write a bulletin about
that. One of the least troublesome, one of the most interesting, and one
which you cannot fail to recognize because it is so "different", is
Mullein. In England it is sometimes cultivated in gardens and called the
Velvet Plant but it grows wild there and abundantly in southern Europe
Mullein is a sun-loving weed commonly found on bare hillsides, worn
out fields, closely grazed pastures, fence rows that are not too
overgrown, and other waste places. It cannot stand much competition,
even by grass, but prospers on dry poor upland soils: clay, gravelly or
even stony ground. We carefully dug up a first-year mullein growing in
an abandoned driveway. It had a stout taproot that penetrated through
the crushed rock and cinders, mixed with a little dirt, into the subsoil; a
few coarse lateral roots; and numerous rootlets. It was equipped to
withstand a long drought and live through the coming winter.
Mullein is a biennial easily eradicated by cultivation in fields and
gardens. It grows from seeds that are undigested and scattered by birds
such as the goldfinch and sparrows, or those occasionally present in
commercial seeds and chicken feed. The first year, it develops a rosette
of soft flannel-like leaves densely covered with fine hairs. The outer
ones are large, long, tapering and pale green. Toward the center they
become smaller and smaller and more yellowish. Livestock will not eat
those hairy felt-covered leaves and the rosette remains soft and green all
In its second year the plant sends up a thick stalk, from 3 to 8 feet tall,
clothed with woolly leaves. At the top is a long cylindrical spike
crowded with buds, and its yellow flowers bloom in procession during
late summer. It produces myriads of little black seeds. In autumn,
mulleins are often infested with black thrips -- tiny sucking insects.
There are about 40 folk names for mullein. Flannel Leaf, Velvet Dock,
Aaron's Rod, Peter's Staff, Candlewick, Torchwort and Big Taper are
some of them. The stalk makes a good cane and, dipped in tallow, they
were used as funeral torches in ancient Greece and during the Middle
Ages. The Romans and, later, European peasants used the dried leaves,
or hairs scraped from the leaves, to make candlewicks.
Although not officially recognized as a drug plant, mullein -- once
thought to be a remedy for leprosy -- contains a mild narcotic and has
been commonly used for home remedies such as a tea, from the leaves,
for catarrh or as a sedative. People with asthma are said to find relief by
inhaling smoke from the dried leaves. As boys, we used to smoke them
and thought we were men. The velvety leaves cause dermatitis to some
persons but country girls used to rub their cheeks with mullein to make
The Moth Mullein, much different, grows in the same sort of places but
is more common in eastern states. It leaves are smooth, with lobes and
teeth along the edges. They are said to repel cockroaches and, in New
England, .were packed among woolen garments to keep out clothes
moths. The flowers, borne on a slender stalk about 2 feet tall, are
yellow or white with violet centers and seem to attract night-flying
moths -- hence the name.
Every tagline we thought of was too corny. Can you suggest one ?
