Fig buttercup is reported to be invasive in at least seventeen states in the northeastern U.S. from Wisconsin to New Hampshire south to Tennessee and, to date, in one western state, Oregon (http://www.invasiveplantatlas.org).
Flowering spring (Apr-May).

The preference is full sun to light shade, moist conditions, and soil containing loam, silt, or calcareous sand. However, Lesser Celandine can survive in moderate shade (where it may fail to flower) and drier conditions. Because the seeds are often infertile (especially for ssp. bulbifer), this species is more readily propagated by its bulbils or division of its tuberous roots. It should be noted, however, that Lesser Celandine can spread aggressively and it is considered an invasive species in many parts of North America.

Eurasia including Europe, Northern Africa, Western Asia, Caucasus, and Siberia
Fig buttercup is a vernal or spring ephemeral perennial plant that spends much of the year (summer through early winter) underground as thickened, fingerlike tubers or underground stems. During the winter, leaves begin to emerge and photosynthesize in preparation for flowering. In the mid-Atlantic region, most flowering occurs from late winter through mid-spring (March through May), depending on conditions. After flowering, the above-ground portions begin to die back and the plants are mostly gone by June. Fig buttercup spreads primarily by vegetative means through abundant tubers and bulblets, each of which can grow into a new plant once separated from the parent plant. The prolific tubers may be unearthed and scattered by the digging activities of some animals, including well meaning human weed pullers, and spread to new sites during flood events.
Fig buttercup is a vigorous growing vernal plant that forms large, dense patches in floodplain forests and some upland sites, displacing many native plant species, especially those with the similar spring-flowering life cycle. Spring ephemerals complete the reproductive part of their life cycle and most of their above-ground development in the increasing light of late winter and spring, before woody plants leaf out and shade the forest floor. Some examples of native spring ephemerals 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 fig buttercup emerges well in advance of the native species, it has a developmental advantage which allows it to establish and overtake areas rapidly.
Fig buttercup is currently found in 20 northeastern states and in Oregon, Washington and several Canadian provinces. It occurs most commonly on moist, forested floodplains and other wet areas.
