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.

We have found Lesser Celandrine (Ranunculus filariasis) in our backyard and would like it to be eradicated. Maybe 50 sf total in two locations. One behind our outdoor fireplace and another in the back southwest corner of the property.
