Pseudosasa japonica, common names Arrow bamboo and Japanese arrow bamboo, is a species of bamboo.
Pseudosasa japonica's common name, "arrow bamboo" or "Japanese arrow bamboo" results from the Japanese Samurai using its hard and stiff canes for their arrows.
This species is native to Japan in Honshu, Kyushu, and Shikoku, as well as Korea.
In the United States it is found in USDA Plantzones 10 through 6, (ie: Florida to New York).
This cold hardy bamboo species (tolerant to 0°F/-17.7°C) grows well both in shade and also in full sun. The culms are typically yellow-brown and it has palmfont-like leaves. Pseudosasa japonica does very well in containers and salty air near the ocean. Because it tends to be more shade tolerant than other bamboo species it is often used by gardeners as an understory to a tree-lined living fence.
