Commentary

Hi, Elizabeth. Thanks for your report and question. In the Portland metro area, there generally aren't invasive removal programs. There are a handful of newly arrived species in Portland that ARE managed, but lesser celandine isn't one of them. That list is at www.portlandoregon.gov/bes/edrr, or feel free to contact me directly at mitch.bixby@portlandoregon.gov.

Thanks again for checking in....

Remedy

For small patches, plants can be dug up in their entirety (be sure to get all roots and the small bulbils that break off to form new plants - you may need to sift through your soil to get these). Do not compost or put in your yard debris bin any below-ground parts of the plant (tubers and bulbils) as they can be spread this way. The leaves and flowers are ok to compost or put in yard debris. For larger patches, digging is impractical and can cause a lot of disturbance; herbicide application may have more success. * Lesser Celandine: National Park Service fact sheet *Lesser Celandine info from West Multnomah SWCD
