Well-known nature author Sten Selander writes that Swedish flora could be divided according to three mountainous regions: mountain pine forest, mountain birch forest, and mountain tundra. Low altitudes boast glacier buttercups are growing on barren rocky areas. In the areas above 1,000 meters, you can find alpine butterwort that is a low growing flower with a strongly developed root system. There is also a lot of moss and other low-growing flowers that usually cover the forests and tundra with a bed-like bloom. Its strong roots and small size are this plant's only chance for survival in the freezing north.
