Lesser Celandine (Ranunculus ficaria) on Apr 7, 2021
Submitter has sample EDRR Status: Local expert notified
Description of specimen
the property is overrun with lesser celandine. we have had some success with soil solarization to eliminate it, but it is so invasive it almost always comes back.
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.
