The Wikipedia article on the Mullein is quite extensive. From it, I learned that the flowers are a source of yellow dye. The plant also has numerous medicinal properties, and it was quickly adopted by native Americans for use against lung ailments.
Its Ukrainian name is korov'iak. Other common names for the Mullein are
- Cowboy toilet paper
- Shepherd's staff
- Bullicks lungwort
- Flannel Mullein
