Reminds me of Valerian as well. The foliage is nice and the sweetly scented pretty white flowers scent your whole garden. It can grow to 5 foot tall so it's great for the back of the border. And because of it's white flowers it's a great plant for a moon garden.
It can self sow to the point of being pretty invasive unless you cut it back after flowering.
I pull out any self sowed plants that I don't want by the root. My cats go crazy for the roots. Valerian, an herb, and a sedative for humans is a stimulant for cats. Though my cats like catnip, they really go crazy for valerian.
