About
Saxifraga longifolia, the long-leaved saxifrage, is a compact, evergreen alpine forming a magnificent, dense rosette to 30 cm across with layers of long, narrow, lime-encrusted leaves. Mature plants produce a large, arching flower spike to 60 cm long covered with small, white flowers in late spring to early summer � plants die after seeding. A spectacular, monocarpic, silver-encrusted saxifrage for a sunny, very well-drained rock garden.
