Care
Watering
The Sardinian buttercup enjoys fresh soil during spring growth. Water regularly in spring, particularly during dry spells. Once established, it tolerates some summer dryness. Avoid excessive water that promotes root rot.
Light exposure
This plant prefers full sun to partial shade. It flowers abundantly in full sun. In hot Mediterranean climates, some afternoon shade can be beneficial.
Soil
Grow the Sardinian buttercup in well-drained soil, preferably calcareous or neutral. It adapts to poor and even rocky terrain. Improve drainage if your soil is too compact or clayey.
Fertiliser
Fertiliser is generally not necessary. If the soil is very depleted, a light application of organic matter in spring is sufficient. Avoid nitrogen-rich fertilisers that promote foliage at the expense of flowering.
Pruning and maintenance
No pruning is strictly necessary. Remove spent flowers to prolong flowering and reduce plant exhaustion. In autumn or after senescence, clean up debris to maintain tidiness and prevent disease.
Diseases and pests
The Sardinian buttercup is generally robust. Watch for powdery mildew in case of excessive humidity and poor air circulation. Slugs can damage young leaves in spring. Good site hygiene and adequate drainage reduce health problems.
Did you know?
The Sardinian buttercup bears flowers of a brilliant, glossy golden yellow, giving the impression that the petals are varnished with grease. This natural phenomenon long intrigued botanists: the cells on the petal surface reflect and concentrate light, making them particularly attractive to pollinating insects and spectacular in the sun.
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.
