I looked up gravel root only to find out it is Joe-Pye Weed, which is how I know it. I did find out how it got that name while writing up this materia medica. It was named after a New England medicine man who used it to cure typhus. Interesting discoveries while doing my herbal studies. I just LOVE this stuff! 

I have Joe-Pye Weed in my orchard – although I believe it is Eastern Joe-Pye Weed (E. dubium). And as you can see from this picture (not mine), the butterflies love it!
