Roses are the earliest delicacies.

Roses grew in China about 5, years ago. According to historical records, Pingyin, the hometown of roses in China, was cultivated in the Han Dynasty and has a history of more than 2, years.

The word "rose" was not a flower name at first, and it was explained in Shuo Wen Jie Zi as "rose, a beautiful stone, a rose and a round pearl." It means that roses are the most beautiful among jade and roses are the most beautiful among jewels. The word "rose" also appeared many times in Sima Xiangru's works in the Western Han Dynasty, for example, in Zi Xu Fu, "The stone is a red jade rose". Therefore, the rose was originally a kind of gem, and its color was purplish red. The time when rose was used as a flower name was the Tang Dynasty, which should be because roses and rose gems are similar in color.

Difference between Chinese rose and rose:

1. Different leaves: Chinese rose leaves are different from rose leaves. Rose leaves are wide, smooth and shiny, with 4-5 leaflets, unclear Ye Jin, sharp serrated edges, and small, thick and dull rose leaves with white soft hairs on the back.

2. The thorns are different: the thorns of roses are long on the epidermis, with large thorns, usually 3-4 in each node, which are easy to break. However, the thorns of roses are stem thorns, which are small and densely distributed. Careless touching will damage the skin and cause bleeding. The stems of Chinese rose flowers have no fluff, and there are few thorns distributed, but the thorns are big, about three or four in each section, and there are curved hooks at the top of the thorns.

3. Different flowers: The rose flowers are relatively large, with a diameter of about 8-1 cm. The petals are single, double and semi-double, and the edges are turned out and warped. However, the roses are small, flat and disc-shaped, and the petals generally have three rounds, and they are wrapped very firmly.

4. Different colors: Chinese rose flowers are colorful, some varieties have stripes, spots and multiple colors, but the color of roses is very single, not as rich as that of Chinese roses, and the common colors in life are purplish red, pink, bright red and white.
