Galanthus Spanish and French Pyrenees in the west through to the Caucasus and Iran in the east, and south to Sicily, the Peloponnese and the Aegean, Turkey, Lebanon and Syria. The northern limit is uncertain because "G. nivalis" has been widely introduced and cultivated throughout Europe. "G. nivalis" and some other species valued as ornamentals have become widely naturalized in Europe, North America and other regions. "Galanthus nivalis" is the best-known and most widespread representative of the genus "Galanthus". It is native to a large area of Europe, stretching from the Pyrenees in the west, through France and Germany to Poland
Chlamydomonas nivalis optimal position in the snow for moisture content, light, and temperature. When in the immotile cyst stage, the "C. nivalis" cells must depend on the flow of meltwater to move it by chance to a favourable area. The temperatures in which this species can survive in ranges from below 0 °C to just above 20 °C. Growth is slow when temperatures are below 5 °C. At 5-15 °C the growth of "C. nivalis" cells can outperform the growth of C. reinhardtii cells. Both species grow at the same rate at 20-25 °C. The growth of "C. nivalis" is suppressed when
