Verbascum

Verbascum thapus  ( Common Mullein, noxious!) by Cherie Luke The genus Verbascum has some good garden plants and one noxious weed that should never be planted.   Verbascum thapus , also known as common mullein, is a member of the Scrophulariaceae, figwort family. Currently  Verbascum thapus is on the “C” list of Noxious Weeds of Colorado.  This means it is already widespread throughout the state, and should at least be suppressed when possible. It is a biennial that reproduces by seed that can live up to 80 years. It is native to Asia but it is thought that it got here by way of Europe. It has long furry leaves and a tall yellow flower stalk. It is well known among herbalists. Mullein tea is a treatment for respiratory problems such as asthma, bronchitis, and chest colds. Because it is a noxious weed, one can harvest unlimited quantities, but be sure that they have not been sprayed. The roots and seeds of this plant are toxic and should never be used for any reason.
