Creeping buttercup

Ranunculus repens
has low creeping stems (stolons) with leaves that are divided into 3 distinct lobes. Flowers are similar to those of meadow buttercup, but they tend to be larger, brighter and less numerous per stem.
Soil moisture tolerances
It is found on sites with 10-20 weeks dry soil per year and 10-20 weeks wet soil per year.
Soil fertility tolerances
Can tolerate sites with a high fertility (>25 mg P/kg or P index 3 or above).
Suitability for floodplain living
Creeping buttercup can be an invasive weed, producing many stolons (horizontal stems) that enable it to ‘creep’ across a site. It is successful in damp conditions where fertility is high. If it is a problem, then there may be a need to improve surface drainage or alleviate soil compaction.
