Edelweiss planting

Leontopodium belongs to Compositae.

Introduction: Also known as edelweiss. Perennial herbs. Plants are covered with white or gray wool. Leaves alternate, entire. Bracts several, around the inflorescence, spreading, forming a star-shaped bract Ye Qun; There are many flower heads arranged in corymbose inflorescences. Originated in high altitude areas of Europe. It is one of the famous alpine flowers and is known as the famous flower in the Alps. Switzerland, known as the "world garden", has designated edelweiss as the national flower; Austria also regards edelweiss as a symbol of honor and friendship. Let edelweiss become the national flower.

Plant height:15-40cm

Propagation: Seeding and propagation by individual plants. It is better to divide plants in spring, and the clustered edelweiss can be potted directly after peeling. Sowing, mainly in spring, the optimum temperature for seed germination is 20 degrees Celsius, and it germinates after 10.

Cultivation: Edelweiss is suitable for growing in fertile and loose humus soil, and attention should be paid to choosing humus fertile soil for basin soil. After sowing, seedlings need to be thinned, and potted plants can be moved when there are three real leaves. In the growing period, the basin soil should not be too wet. Fertilize once a month, and pay attention to the fact that the fertilizer solution can't pollute the leaves. It is best to keep the soil slightly dry in winter.

Appreciation and application: Edelweiss is a precious flower. She has the characteristics of beautiful flowers and leaves, small and exquisite plant shape, bright silver-gray leaves, white inflorescences as snow, simplicity and generosity. At the same time, it has the advantages of drought resistance and barren resistance, and is a perennial herb, especially suitable for planting in rock gardens or potted plants.

alpine plant

Edelweiss and Gentiana are the most famous alpine flowers; But in addition, there are many plants that are also very suitable for alpine environment. It is no accident that the wild flowers all over the mountains are brightly colored; The color of wild flowers is very important for their survival and reproduction. First of all, because of the high altitude and strong sunshine, pigments can block the irradiation of ultra-strong ultraviolet rays. Secondly, weather conditions limit the flight of insects, and plants must strive for pollination opportunities as much as possible. Bright colors are easy to attract insects, otherwise wild flowers can't reproduce. Wildflowers must also multiply rapidly: in summer, hay machines drive into the grassland and start harvesting for the first time. Some plants must produce seeds before this.

Plants and livestock growing in the same environment have different problems. Delicious grass will be eaten before sowing, but those hard and prickly will be let go. It seems that the fate of being harvested is better than being eaten by herbivores. At least plants have a chance to sow and reproduce. Precious plants such as orchids can only survive near cliffs. Other delicate plants have developed roots and can survive under the ravages of hungry animals.

After the ice and snow melt, the rocky land becomes very unstable, without water and nutrition. But in just a few years, some special plants "colonized" this barren land. Mr. Wang's moss will leave a thin layer of humus after death. Humus provides a foundation for the growth of Saxifraga and Stichopus japonicus. The biggest problem of early plants is not the lack or movement of soil: the root of the smallest plant is also one meter long and can grow steadily; If cracks can be found in the rocks, their underground buds are ready to sprout at any time. The smallest tree in the world, the dwarf willow, also has this ability. The trunk of dwarf willow is below the surface, and there are only a few branches on the ground. This peculiar growth mode not only keeps warm, but also protects against water loss when it is windy.

Plants growing on the surface of rocks must overcome the problem of water shortage. Poor soil can't keep water, and strong sunlight quickly evaporates the remaining water. The strong wind that often blows on the mountain will make the leaves of ordinary plants lose a lot of water. Alpine plants have the ability to prevent water loss: some plants are covered with fine hairs, which can resist sunlight and form an air layer to moisturize; Some plants have a waxy protective layer; Succulent plants store water in thick leaves; There are also many plants that form rosettes, shielding each other from the sun. Other plants grow as close to the surface as possible to overcome drought and reduce the damage caused by strong winds. Of course, many plants can have several abilities at the same time.
