Expert tips
The key tip
Ranunculus ornatus prefers rich, cool and well-drained soil in gentle full sun. Don't let the substrate dry out during flowering.
The common mistake
Planting it in poor, dry soil results in rarer flowers and a weak plant.
The pro's trick
Add mature compost at planting time to support flowering without excess nitrogen.
Care
Exposure
Plant the ornate buttercup in full sun for generous and colorful blooming. It tolerates partial shade but will flower less abundantly. Choose an open, airy and bright location with at least 6 hours of sunlight per day.
Watering
Keep the soil moist but well-drained, especially during growth and flowering. Water regularly without allowing water to pool at the base. In summer, increase watering frequency if temperatures are high, then reduce after flowering.
Soil
Plant the ornate buttercup in rich, loose and well-drained soil. Enrich the soil with compost or potting mix before planting. Avoid heavy and compacted soils that would promote root rot.
Fertilizer
Apply balanced fertilizer in spring when growth resumes. An application of well-decomposed compost in late winter is usually sufficient. Moderate nitrogen fertilizers that would favor foliage at the expense of flowers.
Pruning and maintenance
Remove spent flowers regularly to extend blooming. In autumn, cut back dried foliage flush with the ground. Clean up dead leaves around the base to prevent disease.
Diseases and pests
The ornate buttercup fears excess moisture which can cause powdery mildew or root rot. Ensure good ventilation and avoid wetting the foliage. Inspect regularly to detect any signs of disease or infestation early.
Did you know?
The genus Ranunculus, to which the ornate buttercup belongs, has characteristic petals covered with a fine layer of reflective cells that creates a unique pearlescent and luminous sheen. This botanical adaptation, called 'lacquered brilliance,' reflects light so effectively that it particularly attracts pollinators.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
