Land Plants - invasive

Lesser Celandine (Ranunculus ficaria) on May 4, 2011

Submitter does not have a specimen
EDRR Status: Local expert notified

Description of specimen

Small patch, perhaps not even a square meter. One flower noted.

Commentary

Thanks so much for this report, Josh. Considering the infestation is in the riparian area of the headwaters of the amazon, it should probably be considered priority for response so it doesn't spread further downstream. I'll share the report with the City of Eugene and find out whether they can address it.

Thanks, and keep the reports coming!

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
