Despite being the second largest desert in the world at 500,000 square miles, the Gobi Desert features relatively few species of vegetation. The Gobi Desert spans across Northern China and Southern Mongolia. The landscape of the desert consists of sandy soil as well as areas with small stones known as gobi. While the desert is a cold desert, precipitation still falls here less often than other places, with less than 10 inches of snow or other precipitation per year. Because of the soil environment and lack of extensive precipitation, plants must adapt accordingly.

Saltwort grows within arid and semi-arid regions throughout the world but began natively in Eurasia. The plant earns its name from the fact that it is incredibly tolerant of salt. Because of this, according to the website Gobi Desert, saltwort plants survive in the Salt Desert region of the Gobi Desert where few other plants are able to grow. Saltwort plants feature a taproot system that gathers moisture from the surface of the earth, while a deeper set of lateral roots gives the plant stability. Small flowers appear on the saltwort from June until August.
