Yellow Archangel (Lamiastrum galeobdolon) on May 21, 2008
Submitter does not have a specimen
Description of specimen
fA variegated leaf (partially white) and seems to be a creaping plant that sends out runners. It is mainly a shade type plant. The area I described is a spot about 20 feet in circumferance, and I think it has only been there about 2 years now.

I believe the plant you found is called yellow archangel. You can read more about this invasive plant at:

I will forward your report to the East Multnomah SWCD and the Oregon Department of Agriculture.
Unfortunately there are limited resources for weed control in Oregon. In the Portland area, most of the weed control efforts are focused on high priority species like garlic mustard and knotweed. However, as we learn more about the invasiveness of yellow archangel, it may also be prioritized for control, especially if this is a new population that could be eradicated. So, we appreciate your report.
In many cases, concerned citizens will take the lead in controlling certain species or join work parties to help with the battle against invasives. I would recommend you contact the East Multnomah SWCD (www.emswcd.org)if you want to join other weed control efforts in Portland. One fun way to volunteer is to become an “Invasives-Watcher” and look for and report high priority species in the Portland area http://www.westerninvasivesnetwork.org/pages/nature_conserv.html
