Marsh Marigold (above) - vs - Lesser Celandine (below)
Lesser Celandine can be found in open woods, waste areas, meadows, and floodplains preferring sandy soil. It closely resembles the Marsh Marigold and is often misidentified as such.
To tell the difference between the two it's important to know the native Marsh Marigold has only 5-9 petals where as the Lesser Celandine has 8-12, and the leaves of the Marsh Marigold are round sometimes kidney shaped where as the Lesser Celandine which has more of a heart shape.
Marsh Marigolds tend to stay in small bunches and do not have the same sort of underground tuber system that the Lesser Celandine have.
If left to go it will completely blanket the area displacing many native plant species, especially those with the similar spring-flowering life cycle. Some examples of native spring ephemerals which become choked out by the Lesser Celandine include bloodroot, wild ginger, spring beauty, harbinger-of-spring, twinleaf, squirrel-corn, trout lily, trilliums, Virginia bluebells, and many, many others. These plants provide critical nectar and pollen for native pollinators, and fruits and seeds for other native insects and wildlife species. Because Lesser Celandine emerges well in advance of the native species, it has a developmental advantage which allows it to establish and overtake areas rapidly.
