lesser celandine (Ranunculus ficaria)

Posted in Species Profiles

Description: Lesser Celandine is an herbaceous perennial which grows low to the ground with hairless, dark, fleshy, heart-shaped leaves. Rosettes of dark kidney/heart shaped leaves form dense mats on forest floors. Bright yellow flowers rise above the leaves on a single stalk.


Habitat: Lesser Celandine grows in moist alluvial sandy soils found in floodplains, but can also be found in low open woods, meadow, roadsides, and waste areas.


Invasive Traits: Lesser Celandine emerges early in the season and crowds out native flowers with its thick mats of vegetation. Affects native pollinators who feed on native spring wildflowers.


Control: Hand pulling can be effective only when the entire root system is removed. Herbicide can be applied in early spring. Herbicides must be approved for use in aquatic systems.
