Michelle,
Today I visited the ROW off Exit 57, as you correctly identified, I found two 2-3' tall oblong spurge plants! I've attached some photos. I dug up and bagged both of the plants. I will notify ODOT as well and have them keep an eye out. And next year I'll revisit the site and check for any new plants or regrowth. Thanks again for spotting this new invader! I can't say for sure, but this may be the first sighting in Washington County.
Kind regards,
Tyler
