? The history of roses
China has a long history of cultivating roses, and there was a legend of cultivating roses before Xia Dynasty. The exact record of Rosaceae plants was first found in the Book of Songs from the Western Zhou Dynasty to the Spring and Autumn Period 3000-2500 years ago, and the married princess was compared to Tang Dihua.
It was not until the Western Han Dynasty that Rosa was recorded. According to documents, roses were planted in Shanglinyuan in the era of Emperor Wu of the Han Dynasty. According to "Harvest on the Forest", Emperor Wu of the Han Dynasty and Li Juan were enjoying flowers in the garden. When the roses began to bloom, they were smiling.
It is reported that the Romans also planted roses very early. In their paintings, decorations and sculptures, there are many works with the theme of roses, and they also extract spices from roses. Josephine, the queen of Napoleon I of France, loved roses very much, so roses received special attention in France.
