Red Valerian: “Albus"

I don't even understand why a white flowering plant is literally called Red Valerian, but it is what it is. "Albus" is the white VERSION of the red valerian, multiple websites confirm, so, um, whatever.

Anyhow, it's about 2 1/2 feet tall, and pretty as can be in our back garden alongside the path as it blooms for the first time, and, well, all I can say is I. Want. More. The leaves are quite lovely, and it turns out these can be good for erosion control. Plus - perhaps my favorite - it "thrives in poor soils". Wheeee! Considering a small section of our back garden appears to have once been a gravel-filled parking spot (?), maybe that's why it's doing so well hahahaha...

The Missouri Botanical Garden - a great resource for gardeners, by the way - says "Although native to the Mediterranean, this plant has escaped gardens and naturalized in certain parts of the United States, particularly along the west coast."

So can I call this a native? Maybe...
