Boneset Chocolate

When I was in HD buying my Ninebark, I saw this perennial with purplish foliage.  The tag name was 'Boneset'.

 Hmmmm....never heard of a perennial with that odd name.  The tag also  said "TALL HEIGHT" and "DEER RESISTANT".   I decided to buy it.

Once I got home, I did what any respectable gardener would do--I goggled it. 

I found out its common name is 'White Snakeroot'.  I have heard of Snakeroot.  I looked further and I saw pictures of it in bloom.  The flowers reminded me of Ninebark blooms. 

I read that it gets about 4 feet tall at maturity.  I decided to plant it here to break up all the green:

Right now it is so small you can barely see it.  If it gets 4 ft. tall, I think it will be perfect.

Do any of you have this plant?  I would love to hear what you think of it. If you have a link to  a picture in your garden, I would love to see it!
