Question
I have 5 large (36""x 24") single stem plants that showed up in my garden last
fall,  and wintered over in Zone 5 . THe leaves resemble a lamb's ear, but it is
very tall and showy with one flower coming out the center. ANy ideas?

Answer
Hi Gretchen,
Thanx for your question.  It sounds like mullien and I think that is Verbascum thapsus.  It is considered a wild flower in some states and a weed in others.  The leaves in the beginning often resemble the fuzzy lamb's ears.  Here is a link to Google Images that might be helpful to you.  I hope this helps.
Tom
