How Fast do bamboo trees grow?

[Dave]

Established bamboo will send up shoots that generally grow to their full height in a single season, making it the fastest growing woody plant. Several subtropical bamboo species can grow 30 cm (1 foot) per day, with some species having been documented as growing over 100 cm in one day. For the species most widely cultivated in gardens, 3-5 cm per day is more typical. A newly transplanted bamboo plant can take 1-2 years before it sends up new shoots (culms) and will have many seasons of "sizing up" before new shoots achieve the maximum potential height for that species.

bamboo when established can send up a culm/cane 90% of its height in one year..P.edulis (moso) in its best growing area can send up a culm/new shoot 1 meter/39." in a day

bamboo when replanted is said to sleep in year 1
in year 2 it is said to creep
in year 3 its said to LEAP!...but i think imho id say in colder regions it takes longer
