How tall could a bamboo-like (i.e hollow with nodes) tree be ? It should be at very least 1.5m of diameter and walls no more than 20cm thick. The internodes should be 2 to 5 meter long. I think it would need rhizomes etc and grow like bamboo does but you can change whatever you want. Something else I also would like to know is how fast would it grow?

Note that I'm asking only for the resistance to mecanical stresses like tree's own weight or wind even though the first culms would probably be shorter and with several ones wind is less of an issue.

  • $\begingroup$ This is answered on other Stack Exchanges like biology and gardening. Also, there are a lot of different species of bamboo with a whole world of different properties between them. Google is your best friend in this case $\endgroup$ – anon Sep 2 '18 at 18:58

Bamboo is strong so the limit is not strength

Wood in general is pretty strong in tension and compression. Furthermore, it is light so as it gets taller it isn't putting too much stress on itself. As long as the bamboo can increase the radius of its trunk, it can get very tall. Especially if it grows in dense thickets, the protection of other nearby bamboo stalks would help it to survive winds.

On the other hand, bamboo is limited, like all trees, by the mechanics of water transportation. It is hard to move water straight upwards. So, like other trees, bamboo would be limited to about 120-130 meters of maximum height.
