Purple mountain saxifrage (Saxifraga oppositifolia) is a common plant in mountains and highlands. It has the northernmost plant habitat in the world. In Iceland is rather common throughout the country, from lowlands up to an altitude of about 1500 m. It can be found in rocks, cliffs, crevices, gravel and mountainsides.
It is among the first plants to bloom. In lowlands it blooms in April but in highlands as late as June. Today the Purple mountain saxifrage was just starting to bloom in the slopes of Mount Ingólfsfjall, just outside Selfoss.
