Particular attention to flowers arose in ancient times. Flowers are indispensable in the culture of most peoples. Somewhere flowers are used for decoration, somewhere they serve as a sign of attention, and somewhere they are completely revered. It seems that these are just plant reproductive organs, but humanity has made them a real cult, and for many hundreds of years a bouquet of flowers has served as a universal gift in most parts of the world. Scientists have proven that flowers react differently to people depending on how they relate to them. The world’s first flower clock was planted in Switzerland in 1720. The oldest rose in the world grows in Germany. Its location is the Hildesheim Cathedral. It has delighted visitors for more than 1,000 years and its bush almost rises above the roof of the building.
