Description of specimen

I found some mystery plants on my property in the SW hills of Eugene. I had dug them up thinking they were rhododendrons that I could replant elsewhere, but after doing some research, I thought they look more like spurge laurel. I asked for help on Reddit but no one could give me a positive ID, so I contacted Tania Siemens at OSU who confirmed that the plants are indeed spurge laurel.

I live next to Wild Iris Ridge Park, so this may indicate its presence in the park as well. I hate the idea of this plant overtaking native plants in the park, so I wanted to report it to you.
