Edelweiss is a plant that grows in inaccessible places in the highlands. They are found in Europe and Southwest Asia. Can be grown in pots. It grows on calcareous soils. Bees love it for the honeyed flowers. Edelweiss flowers are used in medicine to prepare medicines against diseases of the lungs, heart, etc. The plant is very rare and in many countries it is protected by law. For its protection, for example, in Bulgaria, the "Kozia Stena" reserve was created, which is part of the Central Balkan National Park. The stem of the flower is up to 20 cm high, tufted and covered with hairs. The leaves are strongly narrowed, attached to the stem without petioles and covered with white silky hairs. The lower leaves are larger and gradually decrease upwards. Edelweiss blooms in June-August. Its flowers look like an asterisk with about 10-12 petals arranged in a circle. These are not flowers, but stemmed leaves. If examined under a microscope or magnifying glass, it will be noticed that they are covered with silvery hairs (trichomes), which are so twisted and intertwined that they mask the green color of the leaves. These hairs are dead cells with air cell gaps and when light reflects off them they appear silvery white.
