Tall Purple Flowers, ID?

I have forgotten what this plant is called, can anyone help me? It's over 4' tall, and attracts butterflies, bees, etc.

 

Thanks!

 

Beautiful Pianolady.I now want some of that.

 

That is very pretty and delicate looking.

 

I like it, it's a very stately perennial. Mine looks like a small weed compared to the one you're showing though.

 

Thats really pretty for a weed. I love that color. And the butterfly is pretty too,,,

 

Nice picture Pianolady. I've been eying up the Joe Pye Weed that has filled the ditches around my house.

 

I actually found this plant at the grocery store. It was perfect to hide my pond from the rowdy teens in this area. I don't want anyone knowing I have a pond, which is why it's up near to the house instead of in the back by the street. I do need to move it some, the bees scare my piano students. :-|

 

Pretty weed, pianolady. I would protect the pond anyway I could.

Surely the kids wouldn't mess up the pond, you hid it beautifully well though.
