Some bamboo plants can grow at a rate of 0.00003 km/h.
Bamboo is the fastest-growing plant on Earth. In fact, the Chinese moso bamboo can grow almost a metre in a single day, and can grow as tall as 28m (92 feet).
Bamboo grows in dense forests where little light reaches the ground and there is strong evolutionary pressure to reach the sunlight as quickly as possible.
Bamboo shoots are connected to their parent plant by an underground stem, called a rhizome. This means the shoot doesn’t need any leaves of its own, until it reaches full height. Bamboo also grows with constant diameter. Unlike woody plants, bamboo doesn’t waste energy on growth rings that progressively thicken the stalk. It’s just a single stick, growing straight up.
Yibin City, in southwest China's Sichuan Province, has the largest bamboo forest in the world covering 27 mountains and more than 500 peaks. Hundreds of millions of bamboos form a green sea in the inland area.
