This was acquired as a native plant. I was lucky to find a name tag at the bottom of one of the two specimens planted on the west side of the house, shaded by some getting larger redwood trees.
When I googled this plant, I learned that it will grow in zones 5 – 8, even though it is an alpine or higher altitude native. The last winter here was particularly cold, and only the hardiest of my plants survived. This one has extensive underplantings, so I wonder if that helped keep it just that touch warmer to get it through the winter.
You can see a ‘plant jail’ in the photo, that protects this from deer. Makes me wonder how this exists in the wild. Perhaps there are more plants than deer. Not like here, where the deer have few natural predators.
