Commentary
Dear Ms. Smith,
Thank you for submitting your report to the Oregon Invasive Species Hotline. Unfortunately, the cost to control weeds often exceed the resources available for this effort. As such, we must prioritize the species and areas we treat to maximize the benefits from our limited resources. Your report helps with this process, and allows us to plan future treatments as additional resources become available. So thank you for your report.
Lesser Celandine is certainly a difficult species to control, and requires specific control measures to effective. For more information, check out the Lesser celandine factsheet developed by the Four County Cooperative Weed Management Area. (http://cwmatest.files.wordpress.com/2012/11/celandine.pdf)
Once again thank you for your time and effort in reporting this species.
Sam

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.
