Rose is a woody plant belonging to Rosaceae. According to Shuo Wen Jie Zi: "Rose, beauty of stone, rose and round bead." The explanation is that the name of rose is beautiful, which is the general name of jade and jewelry.

Roses are beautiful and moving, which not only have high ornamental value, but also have certain medicinal value. They have the effects of promoting blood circulation and regulating qi, and can also be made into rose cake, rose wine and cosmetics. It originated in northern China, Japanese and Korean, and now it is distributed all over the world, not only because roses are beautiful and adaptable, but also because of romantic flower language. The flower language of red rose is "love, enthusiasm, love for you"; The flower language of pink rose is "first love, courtship, love, special care"; The flower language of blue rose is "pure love and kindness"

Blue rose is the "blue witch" in people's mouth. This kind of flower is hard-won and very special. It has always been more popular and more expensive than other colors of roses. According to flower experts, naturally growing roses have almost no genes that produce blue pigments, so they cannot naturally grow blue petals. The "blue enchantress" sold in the market is actually the product of artificial dyeing.

The processing method of "Blue Demon Ji" originated from Holland. Flowers can be made of white, pink and light yellow roses, and then mixed with dyes and dyeing AIDS to form a pigment solution and inserted into the solution. In order to color more easily, flowers need to be out of water for half a day before dyeing. Because the branches and petals of roses are similar to human blood vessels, they can absorb and transport water, so that the pigment in the solution will be slowly absorbed by the petals, thus achieving the purpose of dyeing.
