lesser celandine (Ficaria verna) observed in Mill Neck, NY, USA
iNaturalist: kenelma
Summary
iNaturalistWhy it matters This matters because lesser celandine spreads aggressively in early spring before native wildflowers emerge, and once it takes hold in a park or garden it can crowd out beloved natives like trout lily and spring beauty — the kind of plants that make a spring walk magical.
Lesser celandine is a small, yellow-flowered plant originally from Europe that has become a serious problem in American woodlands and wetlands. It blooms very early in spring, giving it a head start over native plants, and it spreads so densely it can take over the forest floor. This sighting at a wildlife sanctuary on Long Island shows it is present in a protected natural area that people visit to enjoy native wildlife and plants.
