Is Black Bamboo Clumping

Black bamboo uses runners to propagate, rather than forming clumps like many other grass varieties. As a result, its growth is considered fast and aggressive. The underground rhizomes easily lead to this plant popping up in unexpected places around your garden and yard.

Is black bamboo clump forming?

Black Bamboo is technically clump forming and has an arching habit. Despite being classed as a clumping variety, depending on ground conditions, Phyllostachys nigra can be somewhat invasive so they are best in areas where there is room to spread, or kept planted in a pot twice the size of the root (even underground).

How quickly does black bamboo spread?

After planting, Black Bamboo tends to take five or six years before it becomes firmly established and the culms reach their full height potential. After planting, the new culms of the black bamboo appear green and may take up to three years before they turn completely black.
