Nice blend of different pink to magenta-red tones in the flowers. Only stops flowering in winter. 4L pot is a real terracotta (not plastic) 21cm pot; 15L is a terracotta-coloured plastic trough 50x23cm.
Saxifraga genus (Saxifrage). These are perennials, biennials and annuals, consisting of about 440 species of evergreens and semi-evergreens. The flowers are mostly white, and sometimes they are spotted with pink, but other colours are also available.
The soil conditions and position of light will depend on the specie. They will also vary in hardiness from fully to frost hardy to marginally frost hardy. Most form tight cushions and flower in early spring, flower stems being barely visible above leaves.
Grown for their flowers and attractive foliage. Excellent in rock gardens, screens, raised beds and alpine houses.
