Care
Light exposure
Position your Silvery Paronychia in full sun to enhance its silvery foliage and achieve generous flowering. It tolerates partial shade but loses some of its characteristic luminosity. Avoid overly shaded areas that promote etiolation.
Soil and drainage
This plant demands very well-drained, light and poor soil. A mix with gravel, sand or pumice is ideal to mimic its native habitat. Avoid heavy soils and standing moisture that cause root rot.
Watering
Water moderately when planting, then significantly reduce watering once established. In well-drained ground, natural rainfall is often sufficient. In pots, let dry between waterings to respect its xerophytic nature.
Fertilizing
No fertilizer is necessary—this plant thrives in poor soils. Excess nitrogen would risk making it too lush at the expense of its compact form and hardiness.
Pruning and cleanup
No pruning is strictly necessary. Simply deadhead spent flowers to extend flowering and remove dead or damaged parts in late winter or early spring.
Pests and diseases
Few problems if drainage is correct. Excessive moisture can encourage rot. Check for scale insects in very dry conditions. Generally very robust and rarely affected by common diseases.
Did you know?
Silvery Paronychia has been a classic in Mediterranean rock gardens since the nineteenth century. Its fine, silvery foliage forms delicate cushions highly prized by landscapers, and it thrives naturally in the cracks of the most arid limestone rocks, where few other plants dare venture.
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.
