Compared with many other green plants, it is very special that the leaves of Hongfeng will turn red in autumn, and many garden lovers will watch it specially after it changes color.

Red maple leaves contain a variety of pigments, including chlorophyll, lutein, carotene, carotenoids and anthocyanins. In the growing season of plants, because chlorophyll is dominant, the leaves are tender green. Autumn comes, the temperature drops, chlorophyll synthesis is blocked, and leaves containing lutein and carotene turn yellow. Red maple is a kind of red leaf tree, which produces a red pigment called anthocyanin in autumn, making the leaves appear red. Therefore, after the chlorophyll of red maple decreases in autumn, its green leaves turn red slowly. However, because of this unique red color, Hongfeng is more fiery and energetic in the depressed autumn and has higher ornamental value.

Through the above introduction, I believe everyone knows why the leaves of red maple turn red in autumn, which is the combination of chlorophyll, but in any case, when there are yellow leaves everywhere in autumn, the red branches and leaves of red maple are really worth appreciating, and I believe they are also good decorations at home.
