Black bamboo (Phyllostachys nigra). A most stunning form, I wish it was cold-hardy in zone 5.
Phyllostachys nigra (full sun or part shade) - Black Bamboo. Perfect, evergreen, privacy border for along fence and front of yard. Have to lay down barrier around planting areas so that it does not spread like wildfire (can be invasive but can also be managed if planned well). Beautiful jet black/mottled green and black bamboo stalks. Wood is very sought after by woodworkers. Functional and pretty.
Semiarundinaria fastuosa 'Viridis'

Of the many options available for running bamboo, my favorites for small gardens are Phyllostachys nigra (black bamboo) and Phyllostachys aurea (golden bamboo) because of their slow growth rate and stunning culm coloring. Golden bamboo works well against a dark backdrop, and black bamboo provides great contrast to lighter plantings in the garden.
