[MAIPC] USDA APHIS considers Ficaria verna to be a high risk weed which could spread across 79 percent of the United States, anticipating possible impacts to threatened and endangered riparian species.[9]

Plant pathogens that have been identified on lesser celandine include the host-specific fungal rust Uromyces ficariae (Schumach) Lev. (Minter and Tykhonenko 2002); downy mildew (Peronospora ficariae Tul.) (Hall 1998); fungal leaf spot (Entyloma ficariae Thüm.

Ficaria verna, (formerly Ranunculus ficaria L. <https://en.wikipedia.org/wiki/Carl_Linnaeus> ) commonly known as lesser celandine or pilewort,[3] <https://en.wikipedia.org/wiki/Ficaria_verna#cite_note-BSBI07-3>  is a low-growing, hairless perennial flowering plant <https://en.wikipedia.org/wiki/Flowering_plant>  in the buttercup family Ranunculaceae <https://en.wikipedia.org/wiki/Ranunculaceae>  native to Europe <https://en.wikipedia.org/wiki/Europe>  and west Asia <https://en.wikipedia.org/wiki/Western_Asia> . It has fleshy dark green, heart-shaped leaves and distinctive flowers with bright yellow, glossy petals.[4] <https://en.wikipedia.org/wiki/Ficaria_verna#cite_note-kooi-4> [5] <https://en.wikipedia.org/wiki/Ficaria_verna#cite_note-newscientist-5>  It is now introduced in North America, where it is known by the common name fig buttercup and considered an invasive species <https://en.wikipedia.org/wiki/Invasive_species> .[6] <https://en.wikipedia.org/wiki/Ficaria_verna#cite_note-6> [7] <https://en.wikipedia.org/wiki/Ficaria_verna#cite_note-:0-7> [8] <https://en.wikipedia.org/wiki/Ficaria_verna#cite_note-8> [9] <https://en.wikipedia.org/wiki/Ficaria_verna#cite_note-:5-9>  The plant is poisonous if ingested raw and potentially fatal to grazing animals and livestock such as horses, cattle, and sheep.[1 <https://en.wikipedia.org/wiki/Ficaria_verna#cite_note-:1-10>
