Arctic Plants Have Adjusted to Climate Changes Yucca plants are commonly found in many deserts, and they withstand hot sun and little water. This makes shallow root systems a necessity and prevents larger plants such as trees from growing in the Arctic. During the short polar summer, plants use the long hours of sunlight to quickly develop and produce flowers and seeds. In the summer, the sun is present almost 24 hours and heats up to about 3C to 12C. Trees cannot survive in the tundra due to a thick layer of polar ice called permafrost. Popular flowering desert plants and shrubs are the desert lily, California poppy, and aloe vera plants. Polar deserts are one of two polar biomes, the other being Arctic tundra.

These contrast nicely with small green fuzzy leaves growing on whitish or gray woody stems. Current Biology, 31(11). Permanently frozen areas on Earth can preserve organisms for tens of thousands of years. When there is more moisture, sedges and grasses become important and form tussock or hillock tundra; willow and dwarf birch may be found between the individual mounds. The succulent leaves grow in a rosette form, and the plant is also called the porcelain succulent. The small trees can grow 20 ft. (6 m) tall, but some only reach the height of a small shrub.
