China's Flora Tour: A role model of the fittest survive

The arid land and dry climate in northwest China's Ningxia Hui Autonomous Region pose a tough challenge to most of the plants that only thrive in mild weather, except for Chinese iris.

Because of its deep-reaching and widespread root system, the flower can flourish with sufficient water obtained by the roots, especially in the extremely arid area. When drought intensifies, the part above the ground will adjust its growth to a smaller and shorter shape so that the roots may gain more energy and nutrient to develop even bigger and deeper.

Also, its long erected leaves well reduced the area that directly exposed to the sun and subsequently keep more water from being evaporated.

This resilient growth pattern not only brings benefit to its own survival in a harsh environment but is also vital to prevent desertification in places like Ningxia. 

China's Flora Tour

From the wetlands along the coast to the dense rain forests hidden in the southwest, China boasts an array of plant species. In this series, we will go on a tour to learn about some of the most representative flora in different provinces and see how they live in harmony with the local geography and climate.
