Spotted plants can be described as varied and strange. Such as white jade evergreen, it broke the common style of evergreen in the past, and the color as white as jade appeared in the center of the leaves, which was elegant and refined. Vine-like kudzu vine and ivy with yellow leaves and white roots hang down like a string of jadeites, which is dizzying.

When you see the white green leaves of the ivy in Phnom Penh hanging in front of the window swaying in the breeze, and the green leaves of the cauliflower taro on the console table glow with little red dot, you may think, how can there be such charming spots on the leaves of these plants? This is called "leaf spot disease" in plant ecology, and there are many kinds. There is a famous foliage plant "alternifolia" which grows in the tropics. There are yellow spots, orange spots, pink spots and brown spots on the pleomorphic leaves, which are embedded in green leaves and have stripes and spots. Botanists call these spots "stars"; Some foliage plants have dark red lines on the green leaves to outline the clear outline of the veins, which are called "dots"; Some foliage plants with golden stripes on their leaves are called "spots".

The leaves of plants are originally green or red, so why do some plants grow such strange spots on their leaves? According to scientists' research, this is because the pigment in leaf cells plays a magician's role. When plants grow, if the chlorophyll production mechanism is blocked in the leaves or the cells produce gene mutation, anthocyanins, lutein and carotene can appear on a certain part of the leaves, which will present colorful wonders on the leaves. This interesting physiological change of plants can also be realized by physical and chemical methods. For example, X-ray irradiation can lead to plant leaf mutation and induce leaf spot disease.

Among the rich and colorful plant resources in China, there are many precious foliage plants that can be exploited. This beautiful wish is waiting for you-young friend, waiting for you to decorate our life more colorful.
