Hi
I have this plant growing outside of my lounge window and I haven't got a
clue what it is. It started growing a fast rate in June and it seemed to
grow at least 30cm per week. It has velvety leaves and a thick single stem
It can be viewed at http://homepage.ntlworld.com/timcass/plant.htm.

Thanks in advance

Mullein, Verbascum thapsus. It's a biennial, growing its flower stem
(which is what you have) in the second year.
