Invasive Species

iNaturalist

Lesser celandine can carpet your yard, garden beds, and nearby stream corridors every spring before you even know it's there — and once it's established, it's nearly impossible to remove without repeated herbicide treatments or years of hand-pulling.

Lesser celandine is a small, cheerful-looking plant with shiny yellow flowers that blooms in early spring, often before most other plants wake up. It originally came from Europe and has spread widely across the eastern United States, where it aggressively takes over forest floors, stream banks, and lawns. This confirmed sighting in Ellicott City, MD helps scientists and land managers track exactly where it's spreading.
