Lesser Celandine (Ranunculus ficaria), is rapidly spreading into Mountain Lakes from its upstream stronghold at Pettoranello Gardens. Though attractive, its aggressive growth habit is ecologically destructive, as it quickly excludes other spring ephemerals.
The end result is a seamless carpet of this exotic species, offering none of the diversity needed to sustain wildlife. Lesser Celandine is sometimes confused with Marsh Marigold, a native that, like many natives, is rarely seen. In a month or two, the Lesser Celandine will disappear back into the ground, remaining dormant until the following spring.
