Hi Sandy , now your getting into my area of knowledge. Unless you have a large are for running Bamboo to grow and don't care how far it goes then you need to install Rhizome Barrier for running Bamboos. There was a debate about this, to me there is no more debate , barrier is the only way to go.A running Bamboo rhizome will grow through a Musa Corm like it was not there.
Also when selecting Bamboo for a Garden please research the best Bamboo for your location. The US seems to be covered in Ph Aureocaulis , there are so many better Bamboos available here. If you live in a more temperate area like Washington State or Oregon then there are many non running clumping Bamboos you can grow.
Have a look at these links
Here is the best guy in Europe , most , not all the Bamboos he grows are available in the US. Jos is a guy I know and trust for Bamoo info.

I've not ordered from these guys but they have many of the rarer Bamboos available in the US. They know and trade with Jos in Europe.

Best of Luck
