Care
Watering
Water moderately during the growing season, avoiding wetting the foliage. In alpine mountain conditions, the plant naturally benefits from soil moisture without excess. Reduce watering significantly in winter. The plant fears water stagnation.
Light Exposure
Plant in full sun to semi-shaded locations. In mountains, it tolerates direct sun exposure thanks to its adaptation to cold, bright environments. Provide light protection from intense sun in Mediterranean regions.
Soil and Drainage
Require very well-drained soil, rich in minerals and gravel. Add coarse sand, gravel, or pumice to replicate its natural alpine conditions. Absolutely avoid compact or organic-rich soils that promote rot.
Fertilizing
No fertilizer application is necessary. This alpine plant prefers poor soils and adapts perfectly to mineral conditions. Excessive nutrient application promotes soft growth and harms flowering.
Pruning and Maintenance
No formal pruning required. Simply remove dead leaves and dried parts after winter. Gently clean up after flowering to maintain a compact and harmonious shape.
Diseases and Pests
Generally very healthy under appropriate conditions. Monitor collar rot in case of excessive moisture or poor drainage. Aphids and spider mites may occasionally appear in greenhouses; mist with clear water if necessary.
Did you know?
The Opposite-leaved Saxifrage is one of the rare flowers that bloom on Arctic cliffs and alpine summits above 3000 m altitude, sometimes the first flower to emerge from snow in spring. Its name 'saxifrage' literally means 'stone breaker' in Latin, because its adapted roots penetrate rock crevices to feed itself.
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.
