Care
Light exposure
Place your Silene flos-cuculi in full sun or partial shade for generous flowering. It tolerates partial shade well but will flower less abundantly in full shade. An ideally lit location receiving 4 to 6 hours of sunlight per day is best.
Soil
This plant prefers moist, well-draining, slightly acidic soil. It adapts to ordinary soil but dislikes prolonged waterlogging. Enrich the soil with potting mix or compost when planting.
Watering
Water regularly during the growing and flowering periods, especially in summer if the climate is dry. Keep the soil moist but not waterlogged. Reduce watering after flowering and in winter.
Fertilizing
A balanced fertilizer application in spring is generally sufficient. In poor soil, a light feeding at the start of the season stimulates flowering. Avoid excess fertilizer, which promotes foliage at the expense of flowers.
Pruning and deadheading
Regularly remove spent flowers to extend the flowering period. Cut the clump back to ground level in late autumn or early winter. This rejuvenates the plant and promotes better regrowth in spring.
Pests and diseases
This plant is generally robust and seldom troubled by pests. Excess moisture may occasionally encourage fungal issues such as mildew. Ensure good air circulation and avoid wetting the foliage.
Did you know?
The name « flos-cuculi » literally means « cuckoo flower » in Latin, because this plant blooms precisely when the grey cuckoo sings in Europe in spring. The finely cut pink flowers are irresistible to butterflies and bumblebees, making it an excellent ally for pollinators in the garden.
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.
