Public Description:

Verbascum, commonly known as “mullein” or “velvet plant”, is a genus of annual, biennial and perennial herbs, rarely small shrubs, and is native to Europe and Asia, with the highest species diversity in the Mediterranean. There are approximately 350 taxa in Türkiye. The plants first form rosettes at the ground level, and then a long stem develops. Biennial plants form rosette leaves in the first year, and stems in the following season. Leaves are spirallly arranged, usually densely hairy, but some species are hairless. The flowers on the stems are usually yellow in color, but there are also species with orange, red-brown, purple, blue or white flowers. The "rotenone (a toxic crystalline substance obtained from the related plants, widely used as an insecticide)" level, which is high in the seeds of mullein, have been used for fishing because of their paralyzing effect.
