It can be difficult to distinguish a clumping from a running bamboo by looking at the canes and foliage but its growth habit should give you some idea as to what type it is. Clumping bamboo will start out just like any ornamental grass - a tuft of foliage. As it matures the clump will get bigger around but the plant won't wander in the garden the way a running bamboo will. With a running bamboo you'll have new shoots emerging from several inches to several feet away from the original plant.

The barrier prevents the spread of the bamboo's rhizomes.

It is not possible to root prune a clumping species to control it. Running bamboo follow the path of least resistance and change directions when they become implimented. Clumpers are persistent and will force their way through obstacles in their outwardly spiraling root path. Never plant a clumping species right next to a foundation or concrete driveway.
Why are the spaces between the culms so close?
The spaces between the culms (canes) are so close most specimens are very unsightly due to the large amount of dead canes and limbs in the interior of the clump. These dense dead canes and limbs cannot be reached unless some of the outside canes are cut away first.

Bamboo types and varieties
To say that there are just two different kinds of bamboo is quite an oversimplification. At the same time, it’s a pretty useful and helpful way to get a handle on this multifarious subfamily of grasses.
Running bamboos
In botanical jargon, running bamboo belongs to the Arundinarieae tribe and has what we call leptomorph or monopodial rhizomes. Basically, this means that the rhizomes extend outward, away from the main plant, parallel to the ground. The rhizomes are shallow and you’ll often see them rising up out and of the soil.
Clumping bamboos
Instead of the long rhizomes that stretch out like tentacles, clumping bamboo typically has tightly-growing rhizomes with a U-shape. Botanists refer to these as pachymorph or sympodial rhizomes. They bend upwards right away to form shoots, rather than building underground networks.
