Commentary

Hi Bruce,

Thanks for reporting lesser celandine. Based on the photos, it looks like this plant is on the verge of a major explosion. I'll follow up on the best response and get back to you soon.I am uncertain of any agency or group in that area that would be willing to lead a response. I think the first step would be to contact the land owners.

Thanks, Tania

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
