Is this Fringed Willowherb? Is it considered Invasive? #757552

Asked June 21, 2021, 5:03 PM EDT

I have this plant growing all over my garden beds and other places. I've been pulling it.....and it still pops back up. My "PictureThis" app ID'd it as "Fringed Willowherb." I didn't notice that it was listed in Oregon as an invasive. So those are my questions - is the ID correct, and is it considered invasive? Thanks. At least it's easy to pull up.

Clackamas County Oregon

Expert Response

Thank you for your question.  Are you able to pull one up and take a photo of the entire plant, including roots?  We need to see how the leaves are attached to the stems.  Have any plants developed flowers?  Those would be helpful, too.  Thank you!

Best,

Thank you for the photos!  All agree it is willowherb.  It is either native or naturalized:  https://horticulture.oregonstate.edu/weed/northern-willowherb

Abby:  the difference in nomenclature is that a 'weed' is just a plant in a location humans don't want it.  It really doesn't have a scientific meaning.  Invasive plants are non-native species which are introduced from other regions, that compete with species often established centuries ago.  If you don't want it, pull it!
