Land Plants - invasive

Lesser Celandine (Ranunculus ficaria) on Feb 19, 2010

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

Description of specimen

Clearly Lesser Celandine (Ranunculus ficaria). Glossy heart-shaped leaves, starting to form buds on Feb 14. The clump was small (<1 m in diameter). I did not have the opportunity to search the area for other clumps.

Commentary

I would be happy to point out the patch, as finding the particular bit of trail can be tricky. I can also help with control.

Hi Amanda,

Thank you so much for reporting lesser celandine. And, thank you for your offer to help! I will follow up to see if anyone can take the lead in contacting the land owner and planning a response. I will contact the SWCD and the Watershed Council to see if they are concerned and would like to have a role in assessing and controlling. Perhaps we can arrange to visit the site, as you suggest! Stay tuned!

Thanks,

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
