Greater celandine (Chelidonium majus) observed in New Salem
iNaturalist: nslator
Invasive Species
Greater celandine spreads readily into garden edges, roadsides, and woodland paths near homes, and while it has a long history in herbal medicine, its sap is toxic and can cause skin irritation — so knowing where it's showing up in your region helps you identify and manage it responsibly.
Greater celandine is a plant originally from Europe and Asia that has made itself at home across much of North America. It has small yellow flowers and produces a distinctive bright orange-yellow juice when its stem is broken. Someone spotted and documented it growing in New Salem, adding a verified data point to the map of where this plant is spreading.
Key Findings
A research-grade (highest confidence) observation of Greater celandine was recorded in New Salem, meeting iNaturalist's community verification threshold.
Greater celandine is a non-native species in North America, originally from Eurasia, and observations like this help track its spread into new localities.
The plant produces alkaloid-rich orange sap that is toxic to humans and animals, making its presence in accessible green spaces a relevant safety and ecological concern.
