Mad Dog, I have meant to ask you this since seeing your post. Are you talking about the kind of bamboo that grows up in the Northeast including PA? If so, that is not really bamboo or even related to the family of Bambusa. Most northerners call it bamboo but it is actually Japanese Knotweed which is very invasive.
While there are some somewhat invasive species of Bambusa called "running" bamboos, virtually all species of Bamboo planted in Florida, including the parks are "clumping" bamboos. They grow out from the center much like an iris, and there are many different varieties, ranging from 15'-60' tall. They are not really invasive at all over extended periods.
