About Silver Pink Rock Rose

Cistus × argenteus 'Silver Pink' · also called Silver pink rock rose, Silver Pink cistus · flowering

Cistus × argenteus 'Silver Pink' is a compact, mounded hybrid rock rose that arose as a chance seedling at Hillier Nurseries, Winchester, around 1910, believed to be a cross between Cistus creticus and Cistus laurifolius. It produces an exceptionally long season of delicate, pale silver-pink flowers up to 8 cm across, fading almost white at the centres, from late spring through late summer; the single most important care fact is that this cultivar needs full sun and sharply drained soil — wet winters are its main killer. It is one of the more moderately hardy Cistus cultivars, suitable for milder UK regions and sheltered city gardens. Cistus is not listed on the ASPCA toxic plant database; classified mildly-toxic here as a precaution.

Ideal humidity: Low to moderate, 30–60%

Watch for — Crown and root rot in wet winters: Cold, wet soil over winter is the primary killer. Plant in fast-draining, gritty soil on a slight slope or raised planting, and cease all irrigation from early autumn. In marginal UK climates (RHS zone H3), grow against a south-facing wall for extra shelter and warmth.

The watering schedule, season by season

Silver Pink Rock Rose is a bog plant adapted to nutrient-poor wet ground — it must sit in a tray of pure water and must never get tap water or fertiliser. The base rhythm for silver pink rock rose is establish with regular watering in the first season; once established, water only during prolonged drought spells in summer., but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Allow the soil to dry completely between waterings. From autumn through spring, rely on natural rainfall and give no supplemental irrigation. Boggy or persistently moist soil causes crown rot, particularly in winter.
