The temperatures are extremely low (less than 50oF/10oC in summer, and around -22oF/-30oC in winter) and rainfall is scarce (less than 1.5 in/40 mm per year). Some desert plants, called ephemerals, wait years for a rainfall event. During the short polar summer, plants use the long hours of sunlight to quickly develop and produce flowers and seeds.

In the winter the opposite light conditions are present. Therefore, other names of the tree include fire stick tree, milk bushy, or Indian tree spurge. The arctic biome (or tundra) is the coldest of all the biomes. Most paleoecologists believe that tundra flora evolved from plants of the coniferous forests and alpine areas as continents drifted into higher and cooler latitudes during the Miocene (23 million to 5.3 million years ago). The most diverse family of desert plants is the daisy family. Characteristics of polar environmentsthe climate, substrates, elevation above sea level, slope, exposure, and proximity to other landmassesdetermine the complex of plant and animal life present in the polar regions. Even though most algae and fungi are no longer classified within the plant kingdom, they are often still included in discussions of plant life. Even so, Arctic plants have a rapid seasonal life cycle. The common names for this small desert-dwelling plant mostly describe the leaves of this succulentred pancake, paddle plant, desert cabbage, and flapjacks. During dry seasons, the bushy plant loses its leaves and relies on moisture stored in its stems to survive hot desert climates. The upward-facing blooms measure 1.5 to 2.5 (3.8 6 cm) wide.

Popular flowering desert plants and shrubs are the desert lily, California poppy, and aloe vera plants. Desert. It is the interplay of these factors during summer that determines whether temperatures are warm enough and moisture is sufficient to allow plants to grow. In addition, human activity brings changes to desert processes directly. Trees cannot survive in the tundra due to a thick layer of polar ice called permafrost.

The tundra biome is located in the northernmost regions of the world, near the Arctic Circle. The evergreen shrub produces dainty yellow flowers, and its large root system absorbs moisture from deep in the desert soil. Identifying features of the desert cactus are its stems with prominent ribs, large white summer flowers, and brightly-colored egg-shaped red fruits. The low precipitation characteristic of tundra regions is comparable to that of deserts at lower latitudes; however, these regions are unlike true deserts in that the low temperatures in both winter and summer limit evaporation. The low-growing, ground-hugging shrub is identified by its large funnel-shaped fragrant magenta flowers, heart-shaped leaves with wavy margins, and large curled seed pods.

Other features of the torchwood copal ornamental tree are its short, swollen trunk with flaky, papery bark, aromatic resin, and an attractive branching habit. When defining biomes it is important to look at vegetation, and a polar ice cap region is normally a place that has very little vegetation, consisting of small shrubs, herbs and lichens mostly, and definitely lacks trees and large shrubs.
