What plants will be able to replace it if I dig it out by hand?

Well, that's going to depend a lot on the conditions at the site. You might check out the Naturescaping resources at East Multnomah Soil & Water Conservation District (EMSWCD)'s website (http://emswcd.org/in-your-yard/naturescaping/). You might also wait until December/January to plant, both because that's easier on the new plants, and because you'll be able to see any returning lesser celandine. It's an awful plant.

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
