I finally identified this beauty. I have an old botanical encyclopedia, and I prefer to identify the flowers, herbs and plants manually for my digital herbarium. Of course there are apps and everything, and sometimes I use them too just to duble check. I know it would be faster and easier. But I love turning over the pages of that book, the smell, the feeling, the beautiful drawings make everything so magical.
Verbascum nigrum (also called black or dark mullein) is a tall biennial, growing up to 1 m. Or even taller.
It has a spear of rich yellow flowers with dark purple stamens covered in hair. The hairy, tubular stamens are dark orange at the tip. The stigma has a green blob on the end.
It can be found on road verges, and grassy places. It prefers well drained calcareous soils. It flowers from June until the end of September.
