Black Bamboo (Phyllostachys nigra)
One of the most stately and beautiful bamboos.
The culms are tall, slender and arching. With age and prolonged exposure to sunlight, they turn intensely glossy black, resembling polished ebony there is more need with this bamboo than most, to remove weaker and thinner stems. However we do find it somewhat more invasive than most of our other bamboos and certainly the roots seem to go deeper than others.
Therefore, although we do not use root barriers, we would advise that for most gardens it would be best to use a fairly deep root barrier for this very elegant and exotic looking plant.
