Bamboo - Clumping

A reader recently asked me "Is there a recommended clumping bamboo for Atlanta? I need one that grows to sixteen feet or more."

Though it grows tall like a tree, bamboo is actually a giant grass. It spreads by means of underground stems called rhizomes. Bamboo plants can expand rapidly if the rhizomes grow several feet horizontally before sprouting an aboveground stem: a culm. Some bamboo species, though, have short rhizomes. They form a clump rather than running throughout a landscape.

A few years ago, Extension agent David Linville gathered information from Georgia bamboo experts and collected it in a publication available at the UGA Extension Service website. It has excellent pictures and descriptions.

Recommended species of clumping bamboo are listed below. The American Bamboo Society lists suppliers of these bamboos.
