Lila Pereszke identified picture 1 as Verbascum. Are pictures 2 and 3 also Verascum? Any ideas as to what variety? I'd like to cultivate these some more.
I believe you nailed it, Ron B. Verbascum blattaria or moth mullein. Wouldn't you know it? I find a really neat plant and voila!, it turns out to be an invasive species. According to http://en.wikipedia.org/wiki/Verbascum_blattaria"V. blattaria has also long been known to be an effective cockroach repellent, and the name blattaria is actually derived from the Latin word for cockroach, blatta." Having been a poor student in "that part of town" years ago, I fully comprehend how "cockroach" and "invasive" go together.
