Land Plants - invasive

Lesser Celandine (Ranunculus ficaria) on Feb 28, 2021

Submitter does not have a specimen
EDRR Status: Population assessed

Description of specimen

Plants are all along this road and most sites are in bloom.

Commentary

None

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

Location

I found lesser celandine, Ficaria verna, all along Glenmorrie Drive. Beginning at the north side at approximately 2600 Glenmorrie Drive, populations occur all along the road to its intersection with the bridge entrance to George Rogers Park. As one gets closer to the bridge, plants are found on both sides of the road.
