2020-05-13: Added comparison of seedpods (easiest way to distinguish the two) and sap (not reliable).
I've been seeing a lot of misidentifications - or perhaps wishful ones - of the invasive Chelidonium majus, greater celandine as the Eastern U.S. native Stylophorum diphyllum, celandine poppy. Here is a visual guide for distinguishing them.

Invasive Plant Profile: Chelidonium majus, Celandine, Greater Celandine
Revised 2015-02-23: This was one of my earliest blog posts, first published in June 2006. I've overhauled it to 1) meet my current technical standards, and 2) improve the content based on the latest available information.
Chelidonium majus, Celandine or Greater Celandine, is a biennial (blooming the second year) herbaceous plant in the Papaveraceae, the Poppy family. It is native to Eurasia. It's the only species in the genus.
It's invasive outside its native range, and widespread across eastern North America. It emerges early in the Spring, before our native wildflowers emerge, and grows quickly to about 2 feet. That's one of the clues to identification. It's also one of the reasons why it's so disruptive. The rapid early growth crowds and shades out native Spring ephemerals.

Web Resource: Invasive Plant Atlas of New England (IPANE)
The Invasive Plant Atlas of New England’s (IPANE) mission is to create a comprehensive web-accessible database of invasive and potentially invasive plants in New England ... An important focus of the project is the early detection of, and rapid response to, new invasions.
