Formation conditions of Saussurea involucrata

Ice lotus needs cold weather and enough moisture in the air to form on clean ice. "Ice flower" is a condensation phenomenon. They need cold weather to form, and there is enough water in the air to form on clean ice. As the temperature rises, the snow on the ice surface melts to form a new ice surface, and a new round of "ice flowers" can be staged again. As the weather gets warmer, the river in genhe city, Hulunbeier City, Inner Mongolia Autonomous Region, which is known as the "cold pole of China", begins to melt, and crystal clear "ice flowers" bloom on the river. Clusters of "ice flowers" are sprouting or blooming, which complement the aquatic plants under the ice, just like "white lotus".
