Ranunculus repens, commonly called creeping buttercup, is a stoloniferous perennial in the buttercup family (Ranunculaceae). Native to Europe and parts of Western Asia and North Africa, it is now widely naturalized throughout temperate regions. It spreads by runners that root at nodes, forming dense mats in moist, heavy, or compacted soils. Leaves are glossy, trifoliate, and often mottled with pale patches; stems are low and sprawling. From spring into early summer, it bears numerous bright, lacquer-yellow, five-petaled flowers about 2–3 cm across that attract early-season pollinators. While occasionally used in rain gardens or naturalized areas, it is regarded as a weed or invasive species in many regions due to its aggressive spread. All fresh parts contain the irritant protoanemonin; sap can blister skin, and ingestion causes gastrointestinal upset in humans and livestock. It is distinguishable from tall buttercup (R. acris) by its creeping habit and rooting stolons.

How to care for Creeping buttercup
Water
Keep soil consistently moist; creeping buttercup prefers damp conditions and tolerates brief flooding but not prolonged drought. In-ground plants often need little beyond rainfall, but supply 2.5–5 cm of water per week during dry spells. In containers, water thoroughly until excess drains, then allow only the top 0.5–1 cm to lose surface moisture before watering again. Avoid standing water in pots to prevent root rot; mulch in beds to maintain even moisture.
Light
Full sun to partial shade. In cool, maritime, or higher-latitude climates, 6–8 hours of direct sun promotes best flowering. In warmer regions, provide morning sun with afternoon shade to maintain leaf quality and moisture. Deep shade reduces bloom and encourages legginess, while intense, all-day sun in hot summers can stress plants unless soils remain consistently moist. Aim for bright light with reliable moisture for balanced growth.
Nutrients
Creeping buttercup is a light feeder and often thrives without supplemental fertilizer, especially in nutrient-rich or compacted soils. In garden settings, avoid high-nitrogen feeds that encourage rampant spread. If growing intentionally (e.g., in a rain garden or container), use a light, balanced fertilizer (e.g., 5-5-5 to 10-10-10) at quarter strength once in early spring only. Prefer slow-release or well-aged compost over soluble salts. Excess fertilization can increase invasiveness and reduce community biodiversity.
Temperature
Hardy in USDA Zones 3–9 and tolerant of severe frost (to approximately −34°C). Growth is most vigorous in cool to mild conditions (about 10–24°C). In hot climates or during heat waves above ~30°C, plants may slow growth, scorch, or go semi-dormant unless soil moisture remains high and light is moderated. No special winter protection is needed outdoors in suitable zones; container-grown plants benefit from frost-proof pots.
