Fig Buttercup (Ficaria verna, formerly Ranunculus ficaria) is an early-blooming perennial with origins in Europe and northern Africa. It is also called Lesser Celandine, and it is sometimes confused with Marsh Marigold (Caltha palustris). More recently, its behavior has transitioned or is in the process of transitioning to that of an aggressive invasive species that threatens bottomlands throughout its adopted range. Even after its invasiveness was recognized, many people did not anticipate that it would behave invasively in the South, as it has begun to do. Be a Citizen Scientist— We are asking you to help us scout areas near you where it is likely to be found, so that emerging infestations can be documented, treated and monitored.
