Bamboo is said to be one of the fastest-growing plants on Earth with reported growth rates of 100 cm (39 in) in 24 hours.
These bamboo sprouts started poking out in my yard and within a week – two at most – I went to look at them again, but couldn’t find them. I was looking for these 2 foot sprouts and they had grown taller than me! They are now AT LEAST 20 feet tall and new ones are coming up all of the time. I am sure that if I sat there long enough, I could watch them grow! I have heard that in some areas, you can actually hear bamboo growing!
