Saxifraga

 

a genus of plants of the family Saxifragaceae. The plants are perennial, sometimes annual, herbs. The leaves are usually in rosettes. The flowers are in corymbs or panicles; they are rarely solitary. There are approximately 350 species in the temperate and cold belts of the northern hemisphere and in the Andes. In the USSR there are approximately 80 species, distributed primarily in the arctic and in the mountains of the Caucasus (the alpine belt). Many species grow in the crevices of rocks. The most common species are Saxífraga hirculus, S. punctata, S. nivalis, and S. oppositifolia. Many species are grown as ornamentals in gardens; some are cultivated indoors in hanging baskets (for example, S. sarmentosa).
