mosses and shrubs
Plant life on the tundra consists of short clumps of liches, mosses, shrubs and surprisingly, several hundred species of flowering plants. These plants are all adapted to cold, windy climates, and have shallow root systems to take advantage of the thin layer of thawed soil above the permafrost. The majority of these only thrive during the summer months, but some of the hardier mosses and lichens survive the winter buried under an insulating layer of snow (the tundra biome).
During the short summer months, the tundra is a riot of color as hundreds of flowering plants grow in short clusters amoung the rocks and mosses. These flowers are dependant on the lakes and bogs that appear in the warm season, and they disappear during the dark winter months. The majority of these plants do not grow more than a few inches tall, an adaptation for growing in a cooler climate (Blue).
