What is Rakkyo-yadake

Rakkyo-yadake (Scientific name: Pseudosasa japonica var. tsutsumiana yanagita) is a species of bamboo in the genus Pseudosasa, native to Japan. It was found in the garden of Tsutsumi's residence in Mito City and was published by Yanagida in 1934. The height of the culm is 2 m and the diameter of the culm is about 1.5 cm. The internodes of the culm are swollen like those of Allium chinense (Rakkyo or Chinese onion, scientific name: Allium chinense) ,. The leaves are bamboo-shaped. Its Japanese name is a variant of Pseudosasa japonica (Japanese name: Pseudosasa japonica), because the internodes of the culm resemble those of the Chinese chinense. Because of the unusual shape of the culm, it is used in Japanese gardens, as a potted plant, or cut into pieces to be used as chopstick rests or pole supports. It is not edible.
