Saxifraga cuneata subsp. paniculata, commonly known as White Mountain Saxifrage, is an evergreen perennial herb. It is native to the high mountain regions of Spain. Saxifraga paniculata thrives in alpine and subalpine habitats, often found in rocky crevices and limestone scree. This species typically forms low, cushion-like mats with rosettes of fleshy leaves. The flowering stems reach 10–30 cm in height, bearing clusters of star-shaped white flowers, approximately 1 cm across, with purplish or red dots. The blooming period extends from mid-to-late June to early August, with the flowers being perfect, containing both stamens and carpels.

White Mountain Saxifrage is valued for its resilience to harsh conditions, such as its ability to close leaf rosettes to prevent photoinhibition and dehydration. Its ornamental appeal lies in its attractive foliage and delicate flowers, making it a popular choice for rock gardens, alpine houses, and as ground cover in well-drained areas. It requires sharp drainage in alkaline or neutral soil and prefers part shade, although it can tolerate full sun in cooler climates. While it is generally hardy, it is susceptible to root rot in excessively wet conditions, particularly during winter. Cultivars with the Royal Horticultural Society’s Award of Garden Merit include ’Southside Seedling’ and ’Winifred Bevington’, among others.CC BY-SA 4.0
