We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
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.
