Moth mullein

Verbascum blattaria, the moth mullein, is a pretty, dainty flower that grows to 18-60 inches in height. Superficially, it is  quite different from the other verbascum growing round here, V. thapsus, that can reach 7 feet. See here https://www.blipfoto.com/entry/2193093971079595376
Two visually different plants in the same genus, but different species.
