Saxifraga rosacea, or Irish saxifrage, is a herbaceous plant in the family Saxifragaceae. It spreads by stolons, forming a compact cushion of short leafy shoots. Flowering stems may be up to 25cm tall, bearing 4-5 white flowers with petals 6-10mm long.
Most Saxifraga arendsii hybrids tend to like fresh soil, so you should water regularly, especially during longer dry periods. Always water the plants from below, never over the leaves. The water can accumulate in the rosettes, which can lead to rotting and fungal diseases. For the same reason, a permanently damp substrate or even waterlogging must be avoided at all costs. During planting, it is advisable to mulch the area with bark mulch, gravel or similar, so that the soil does not dry out too quickly, and you need less watering.
Basically, you only need to fertilize Saxifraga arendsii hybrids in very poor sites or when there are deficiency symptoms. To do this, spread some compost under the plants and work it gently and carefully into the soil so as not to damage the roots.
Most varieties should be planted out in early autumn or late winter. For the best results grow in moderately fertile, well-drained alkaline (chalky) soil, in full sun or semi-shade. Incorporate horticultural grit at planting time to improve drainage.
Regular pruning is not necessary, but dead leaf rosettes and withered stems should be removed promptly.
