Moso Bambooπ
Phyllostachys edulis
γ’γ¦γ½γ¦γγ―
A large bamboo native to China, introduced to Japan in the mid-Edo period (18th century). The most widely distributed bamboo in Japan, its rapid expansion via underground rhizomes has become a problem, while its bamboo shoots (AprilβMay) are prized as food. Culms reach up to 20 cm in diameter and over 20 m in height. The timber is used for building materials, crafts, musical instruments, and charcoal.

- βLeaves are narrow-lanceolate, 2β3 per branchlet
- βBamboo shoots emerging through the ground in spring are covered with brown hairs
