Arrow Bamboo
Pseudosasa japonicaAlso known as Japanese Arrow Bamboo, Metake, Yadake
Arrow bamboo forms dense, vigorous evergreen thickets of stiffly upright culms clad in long, glossy, palm-like foliage. Historically harvested by Japanese samurai to craft durable, straight arrow shafts, it spreads by persistent underground rhizomes that stabilize moist soils along forest margins and ravines. Unlike many delicate bamboos, it thrives in shaded woodlands, tolerates strong coastal winds, and survives hard winter frosts with minimal leaf burn.
