Koelreuteria paniculata is a perennial tree or shrub. It belongs to the Sapindaceae family. It was named the soap tree because of the unique properties of the bark, which contains saponins.Saponins have a bleaching property that was previously actively used. Now the plant attracts more with its external data. The lush rounded crown looks neat both in city squares and in home gardens. In the wild, it grows on the territory of Japan, China, and Israel. It can reach 3-18 m in height. The bark is gray with a brown tint. Blooms 2 times a year. Since the beginning of spring, it is covered with bright burgundy flowers. 2 times flowering occurs before the formation of the seed pods. The flowers can vary from yellow to greenish tint. Kelreiteria, whose leaves have a toothed edge, is covered with bright red-maroon leaves in early autumn. In summer, they are painted in emerald color. By autumn, the fruits ripen in the form of a seed box. In the wild, they are carried by the winds, helping the tree to reproduce. The boxes resemble Chinese lanterns, painted in lilac color. The degree of their maturity is determined by the brightness of the shade. In late autumn, they turn bright red or bright lilac. The inflorescences consist of 4 delicate petals that attract bees. The kelreiteria tree is recognized as a good honey plant. At high humidity and air temperature above 26 °C, the plant begins to produce antibacterial biological components. They move through the air and have an antiviral effect. The plant is propagated by cuttings, seeds and layering. The seeds are pre-soaked, and then subjected to forced hibernation. They are placed in a temperature no higher than 4-5 °C. The wintering period does not exceed 28 days. Seeds are planted in moist soil in early spring. After the sprouts grow by 4-5 cm and they will have the first leaves, they can be transplanted into their own pot or open ground. But it is better to let the kelreiteria grow and gain strength in greenhouse conditions, so that it does not get sick in the open air.
