Many bamboos only flower/seed every 100 yrs or so, then they usually die, so seed is fairly rare. Growing from culms is the usual way. Depending on your location, many can get 30 ft tall.

Check out the bamboo forum at gardenweb.com for lots of info. But beware! These guys are OBSESSED! <img src="/images/graemlins/smile.gif" alt="" />
