ID this plant
Can you tell me what this plant is? It appeared in July and has grown to 10 ft tall. I've attached 2 pictures. Thanks
Multnomah County Oregon plant identification
These white umbel-shaped flowers are difficult to identify confidently using photos. As one remote possibility is toxic, I suggest you protect your skin when removing it. Whichever plant it is, you don’t want seeds to shatter everywhere, so remove it before that time. Possibilities include Anthriscus sylvestris, known as cow parsley, wild chervil, and Myrrhis odorata, with common names cicely, sweet cicely. I doubt it is Queen Anne’s lace, hogweed, or hemlock, but it’s best to be careful. Here is a page from the Forest Service about these look a-likes: https://www.fws.gov/midwest/news/PlantsToAvoid.html Anise, Pimpinella anisum, is another possibility: https://plants.ces.ncsu.edu/plants/pimpinella-anisum/ My suggestion is that you remove this volunteer now. If you want one of the herbs that look similar, purchase the seeds so you can be more confident what you are growing.
