Care
Watering
Water regularly when planting and during the growing season, keeping the soil moist without waterlogging. Once established, Alpine Erinus tolerates relative drought well thanks to its mountain origins. Reduce watering in winter, especially in humid climates, to prevent rot.
Exposure
Place Alpine Erinus in full sun or partial shade for optimal flowering. It particularly appreciates bright exposure that promotes abundant blooming and compact growth. In warm climates, afternoon shade can be beneficial.
Soil
Choose light, well-drained soil that is poor to moderately fertile. Incorporate gravel or coarse sand to improve drainage, which is essential to prevent stagnant moisture in winter. Slightly acidic to neutral soil is ideal for this alpine plant.
Pruning and tidying
After flowering, remove dead flowers to extend the blooming period and maintain compact growth. Light pinching in spring encourages branching and better overall shape. In late winter, remove any dead or frost-damaged parts.
Fertilizing
Alpine Erinus appreciates moderate feeding in spring to support flowering. Use diluted balanced fertilizer or low-nitrogen fertilizer to avoid excessive growth at the expense of flowers. Overfed plants become less floriferous and less hardy.
Diseases and pests
Watch for excess moisture that can promote root rot or fungal diseases. In poorly drained soil or very humid climates, yellowing or soft leaves indicate moisture problems. Pests are generally rare; good drainage prevents most issues.
Did you know?
Alpine Erinus is a small alpine marvel that has naturalized on old walls and rocks in European mountains for millennia. Its Latin name 'Erinus' may derive from ancient Greek, and its ability to flower generously despite rocky conditions made it a favorite of alpine gardens and rock gardens since the 19th century.
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.
