In North America, do not confuse with very-similar-named (and very-similar-looking!) without-adjective celandine poppy  Stylophorum diphyllum.   Although members of separate genera, both are part of poppy  family Papaveraceae.

And do not confuse either with very-similar-named lesser celandine / fig buttercup  Ficaria verna.   Although together the three species are members of two separate families, all three are part of barberry/​buttercup/​poppy  order Ranunculales.

Native to most of Europe, and temperate regions of North Africa and western Asia.   🌎︎ Map by county (🇺🇸 USA-48) (colors).   Invasive > 🇨🇦+🇺🇸 Canada+USA Invasive > report it! Invasive > 🇺🇸 USA Invasive > Michigan
