Bamboo is a grass.
Bamboo is a very fast growing form of a woody-stemmed grass. Giant bamboos are the largest members of the grass family. There are about 1439 known species of bamboo with new species identified often.Bamboos are some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow 35 inches within a 24-hour period.
The hollow central stem with its many joints is called the culm. Bamboo has rhizomes, large underground stems that spread out rapidly through the soil. The result is a dense, interlocking web of fibers that holds topsoil firmly in place. It is an excellent soil erosion inhibitor.The bamboo plant’s root system creates an effective watershed, stitching the soil together along fragile river banks, deforested areas and in places prone to mudslides. It also greatly reduces rain run-off.
