I've never been to Portland Oregon, but here in Virginia it looks like velvetleaf. Is it a noxious weed?? I guess it depends on who's defining what's noxious. Is it invasive? Is there a difference between noxious and invasive? Native or non-native? I think you can get a bunch of different answers depending on local /state and/or federal regulation - if regulation is important to the answer. Then, outside of that there's local terminology tradition.
