6'-12". Don't expect miracles when growing from seed. I've grown several bamboo from seed and the most vigorous -- Moso -- took about 5 years to get as tall as me.

Lol. Now you have me wondering about where I can get a risome. Instead of seeds.

Growing from rhizome is often only marginally better than growing from seed. What you need to do is buy an actual division if you want to see it attain any significant height in the next 5 years. There is a reason that bamboo plants can seem pricey, and it has to do with how much time the grower has to invest to have a salable plant.

your point is well made. I will look into some #5 size plants. As I understand it from the various sites that is about 5 years old and up to 7 feet or so.

Jeff-

When I first got into growing bamboo, I tried growing from seeds (when they were available) and rhizomes. It was fun, but not a good way to have a decent size plant quickly. Hope you find something nice at a reasonable price. What part of the country do you live in?

South Texas. We have river cane that is very happy. Despite us being on a hill miles from any water body.

That species should grow well for you. My Zone is a little too cool for it, but I would love to be able to grow it. If you are looking for a source, these nurseries may have it:

Checking it now. Thank you
