Been letting these beautiful and rather large plants to grow for a couple of years now on the property and was hoping someone knows what it is.

Mullein - Verbascum

Wow that was fast thank-you very much.

With your lead I was able to pinpoint exactly what it is. Verbascum
pulverulent or common name Hoary Mullein broadleaf

yeah I do not know it well enough to id the variety , but I knew it was Mullein. I just looked it up a week ago for someone else.

I am sure many members on here could though and still may weigh in sooner or later. They are pretty good at identifying things around here.
