Valentine's Day roses are mainly red, symbolizing passionate love and passion. Besides, there are white, yellow, orange and pink roses. But do you know that there is a mysterious black rose in the rose family, which is very popular among young people in recent years because of its unique personality. At first glance, it's unremarkable, but after careful taste, I find her mysterious and beautiful. At present, there are two kinds of black roses on the market, one is called "black magic". The other is called "Black Beauty", with a slightly smaller pattern, but more exquisite and unique, with a thick black and red color and a velvet luster of black gold.

In fact, black flowers in nature are very rare, especially real black flowers do not exist. The main reason is that black flowers can absorb all the light waves in the sun, and the temperature rises rapidly in the sun, so the tissue of flowers is easily damaged. So we often see red, yellow, orange, white and other colors of flowers. This is because these flowers can reflect red, orange and yellow light waves with more heat in the sun to avoid burning delicate flowers. It is a kind of self-protection function of plants, but black flowers do not have this ability, so they are gradually eliminated in the long-term evolution process. So the black flowers we see are actually dark red or purple flowers close to black, that is, "red is black, purple is black" in daily life, so are black peonies, black tulip and black chrysanthemums, and so are black roses.
