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

Description of specimen

The plants were in full bloom Feruary 18, 2010. They have spread throughout much of the front yard of the home. The house is currently vacant. I have forwarded the information to Douglas Soil and Water who have been treating many of the weed populations in Douglas County.

Commentary

Dear Julie,

Thanks so much for submitting this report to the hotline and also forwarding it to the SWCD. If possible, please let me know how they respond. I am encouraged to hear they already have a control project in place for this species.

Thanks and keep on reporting!

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
