Growing up in Yunnan, China? Can bougainvillea trees in Guangxi and Southeast Asia grow 3.5 meters high a year? Called "miracle tree" at the 7th World Forestry Congress? Light wood, which grows in Central and South America, grows faster than flowering trees. Can it grow 5 meters in a year? But the absolute champion of the growth rate of woody plants is Phyllostachys pubescens? It takes only two months to grow bamboo from bamboo shoots, and it is as high as 20 meters, about six or seven stories high? Can it rise 1 m during the peak growth period? So there is a saying of "mushrooming"?

The growth of bamboo is special. Is it elongated one by one? How many thick bamboo shoots and how many thick bamboos are long? Once bamboo grows, it doesn't grow tall? All trees grow at the tip of the bud, which gradually thickens and elongates. After decades to hundreds of years, it will gradually become thicker and taller.
