Black bamboo (Phyllostachys nigra) lends dramatic contrast with culms that age from olive to glossy ebony by their second or third season. A fast, running bamboo, it forms elegant, feathery screens 20–35 ft tall in mild climates (often 10–15 ft in containers). Give full sun to bright shade; more sun deepens the color, while light afternoon shade protects leaves from scorch in hot zones. Plant in fertile, well‑drained soil and water regularly the first 1–2 years; thereafter keep evenly moist in summer. Because it spreads by rhizomes, install a high‑quality barrier 24–36 in deep, left 2 in above grade, or commit to yearly rhizome pruning. Thin older, dull culms in late winter to showcase black canes and improve air flow. Top‑dress with compost and feed a balanced, slow‑release fertilizer in spring. Mulch to keep roots cool. In zone 6–7, site out of winter wind; dieback may occur after severe cold, but plants usually resprout. Excellent as a living screen, accent, or in large troughs on patios; check local regulations where bamboo is restricted.
