Plant identity, anyone?
This plant decided to make it's home in my front bed. I've done some searching, but haven't found a satisfactory look-a-like. It's almost 6' tall now. I think I like it and want to move it elsewhere, but first I'd like to know what it is.
6' and growing
the stem is very thick and not round, but not square either (at first I thought it was in the mint family because the stems looked more square)
leaves are smooth edged and somewhat glossy
flower is "spear" shaped; this is the largest I've seen the flower so far
