Also called desert sage, this purple-flowering heat-tolerant plant is a low-growing woody shrub with deep blue-violet flowering spikes. Only a thin layer of soil, called the active layer, thaws and refreezes each year. Net photosynthesis (net carbon uptake) continues to be positive during drought until the leaf water stress declines to the range of -21 to -29 bars, which is considerably below the . The desert shrub is identified by its rounded, spreading habit, silvery gray-green leaves, and bright yellow summer blossoms that appear after rainfall. Studies of nine flowering plant species from Svalbard, Norway, suggest that Arctic plants are able to shift long distances (via wind, floating sea ice, and birds) and follow the climate conditions for which they are best adapted. The following excerpt was taken from Chapter 6. Precipitation This region can also be called a cold desert due to its lack of precipitation. Deserts are also characterized by having plants that grow very slowly. (The cold climate and short growing season also prevent tree growth. Its commonly found alongside other desert plants such as Joshua trees, creosote bushes, and saltbush scrubs. Circulation of air masses around the Earth transports industrial pollutants from temperate regions into the Arctic and Antarctic. One of the most stunning flowering desert plants is the Mojave asteralso called the Mojave woody aster.
