Edelweiss: a famous flower in the Alps

  In the Alps, edelweiss is respected and loved by people. Austria and Switzerland regard edelweiss as their national flower. In Switzerland, everything from chocolate packaging to printing on napkins, from children’s clothing to hotel key chains, and even street trash cans, are all decorated with edelweiss patterns. The author has seen edelweiss several times in a mountain village in Switzerland, but unfortunately they are all planted randomly. It wasn’t until I went to the Jungfrau Mountain to see the true appearance of edelweiss in an alpine botanical garden built on the hillside.
  Edelweiss is native to Western Europe. It is also known as Edelweiss or Centella vulgaris. It is a perennial herbaceous alpine plant belonging to the Asteraceae Edelweiss. In the Alps, only edelweiss, a plant of the genus Edelweiss, is widely distributed, so people can hardly admit it wrong.
  However, it is different in China. To ask whether China has edelweiss, the answer can be either “Yes” or “No.” If “Edelweiss” only refers to the plant of Alpine Edelweiss, then it is not distributed in China, but if Edelweiss is regarded as a large group of plants of the genus Edelweiss, this group is still relatively common in China.
  China’s edelweiss is not only rich in species, but also has a slightly different growth environment. For example, velvet edelweiss usually grow on alpine grass slopes or meadows, mixed with other herbs, and can be seen in the mountains in the suburbs of Beijing; Silverleaf Edelweiss prefers moist grasslands and marshes, and is commonly found at the edge of wetlands on plateaus in southwestern China; weak Edelweiss is distributed on the Qinghai-Tibet Plateau and grows near the snow line.

Have good quality

  In fact, edelweiss is just an unobtrusive wild flower. Why do people in the Alps like it so much? The English name of edelweiss is “edelweiss”, which means “noble and pure white”. As you can see from the name, they have beautiful qualities.
  In addition, edelweiss has another meaning-toughness. If you pick an edelweiss and put it in your diary, even after five years, ten years, or even longer, the entire plant will always maintain its fluffy and white form. This long-lasting discoloration makes people regard it as a symbol of eternity.
  It does not change color after drying. This is actually a strategy adopted by edelweiss in order to adapt to the alpine environment. A hairy body helps plants retain the heat in the body for longer. Also to prevent frostbite, edelweiss reduces the water content in the plant, which is equivalent to increasing the concentration of liquid in the cell to improve cold resistance. There is not much water when you are alive, and there is not much water when you die, and the difference between life and death is not so big.
  Another strategy for edelweiss to cope with the alpine environment is to make the body less green, that is, to reduce the content of chlorophyll and change the shape and distribution of chloroplasts. In high-altitude areas, there is strong sunlight during the day, and plants may be harmed by light, and reducing the ability and efficiency of photosynthesis is an effective countermeasure.
