Abstract Lesser celandine (Ranunculus ficaria) is an ephemeral perennial introduced to North America from Europe for ornamental use. This species is becoming widespread in shady, moist woodlands and lawns in the northern United States and southern Canada. Despite its invasive attributes, lesser celandine continues to be marketed by the nursery sector. A hardy and easy plant to grow, lesser celandine has a dense compact growth form that makes it ideal for border plantings and showy flowers that… 

Do multiple mechanisms drive the dominance of an invasive plant (Ranunculus ficaria, Ranunculaceae) along an urban stream?1

R. ficaria has some role in driving ecosystem change, and that removal of these populations will help restore some native species, possibly through competition for space and/or light.

Early-Season Treatment of Fig Buttercup (Ranunculus ficaria)

Control of fig buttercup led to an increase in cover of Japanese stiltgrass, an invasive grass, and glyphosate applications under three early phenological phases (preflowering, early flowering, and 50% flowering) were tested.

Allelopathic effects of invasive species (Alliaria petiolata, Lonicera maackii, Ranunculus ficaria) in the Midwestern United States

Differential allelopathic effects of these invasive species, which varied with test species and experimental conditions, showed differential allelopathy effects of this invasive species.

Soil characteristics drive Ficaria verna abundance and reproductive output

It is suggested that soil texture and slope can help explain higher abundance and reproductive outputs in F. verna and can help management by identifying areas likely to support dense infestations.

Alguns Aspectos Biológicos da Planta Daninha Lesser Celandine (Ranunculus ficaria)

Lesser celandine (Ranunculaceae) is a perennial weed with tuberous root. Tubers are the most important means of reproduction and dispersion of this weed. In recent years, it has spread into wheat

Root fungal communities associated with better performance of an invasive spring ephemeral

Root-associated fungal communities consisting of dark septate endophytes and fungi typically associated with ericoid mycorrhizae had a significantly higher average biomass and bulbil counts than plants colonized by parasitic root mycobiota, and fungal colonization was not shown to be associated with differences in the number of R. ficaria tubers present.

Some biological aspects of the weed Lesser celandine (Ranunculus ficaria)

The results obtained showed that the highest percentage of germination occurred when tubers were stored for more than 2 weeks at 4 or 8 oC, and the optimum temperature for germination differed in large and small tubers, as well as the effect of planting depth on sprouting of the tubers.

Leaf Litter Depth has only a Small Influence on Ranunculus ficaria (Ranunculaceae) Biomass and Reproduction

R. ficaria's ability to maintain production across a large range of litter depths may provide a competitive advantage over plant species not adapted to varying litter depths.

Comparison of allelopathic effects of five invasive species on two native species1

Overall, L. maackii had the strongest effects, followed closely by C. orbiculatus, which was then followed in turn by R. ficaria, providing further support for the allelopathic potential of L. Maackii.

The showy invasive plant Ranunculus ficaria facilitates pollinator activity, pollen deposition, but not always seed production for two native spring ephemeral plants

The results indicated that this invasive species increases pollinator activity and conspecific pollen deposition on sympatrically flowering native ephemerals, but may have differential effects on native seed production.




A morphometric analysis based on study of 319 specimens from forty-seven herbaria indicates the presence of five entities reasonably referable to the subspecies accepted in Europe, and all five subspecies occur in the United States.

Ranunculus ficaria L. sensu lato

The taxonomy, nomenclature and typification of the segregates of Ranunculus ficaria L. (Ranunculaceae) in Europe are revised, taking particular notice of their biology. Five subspecies are recognised

Recruitment and growth of herb-layer species with different colonizing capacities in ancient and recent forests

The extent of seed limitation is probably the main cause for the different coloni- zation capacities of the species investigated, and performance of A. nemorosa and R. ficaria was not affected by any of these factors.

Recruitment and growth of herb‐layer species with different colonizing capacities in ancient and recent forests

Seeds and adults of two species of Anemone nemorosa and Primula elatior and two species with high colonization capacities were introduced in ancient and recent forest sites within the Muizen forest (Belgium).

Disturbance by mowing affects clonal diversity: the genetic structure of Ranunculus ficaria (Ranunculuaceae) in meadows and forests

The higher level of clonal diversity in meadow plots is most likely due to the effects of disturbance by mowing, which increases the dispersal of bulbils and promotes the establishment of new plants in meadows compared to forests.

Checklist of dicotyledons, gymnosperms, and pteridophytes naturalised or casual in New Zealand: Additional records 1997–1998

Nine species are reported as additional or newly substantiated fully naturalised records for the flora of New Zealand during the 2‐year period 1997–1998, and thirty‐eight additional species that were previously known from few collections are given extended distributions.
