Report #526 - Report: Lesser Celandine (Ranunculus ficaria)

Lesser Celandine (Ranunculus ficaria) on Mar 31, 2010

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

Description of specimen

patch 2-3 m long, 1-2 m wide along roadside. Currently in full bloom. In a ditch and up the road bank. Looks to be on private land or on road right-of-way. On oak hill Rd; some tree canopy, east facing slope so shaded and fairly moist. Near many wet prairie remnants/mitigation bank areas. Would hate to see this spread!

Commentary

Dear Amanda,

Thanks for your eagle-eyes for lesser celandine. The Upper Willamette CWMA is planning heightened outreach around this plant, and are particularly interested in mapping it out and taking a strategic response. It seems like this plant could easily be spread along Oregon's soggy ditches; keep the reports coming and I'll try to prevent that from happening!.

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
