"Large perennials; culms green, woody, up to 80 dm tall, 3 cm in diameter, smooth to ribbed-striate, glabrous, internodes 7.5-20 (-32) cm long at base, fringed by a dense ring of purplish to brown hairs just above the node, nodal ridges moderately prominent, sheath scars as prominent as the nodal ridges, thin, flared, glabrous, but usually fringed with brown hairs; sheaths greenish brown to pale brown or pale reddish brown, usually sparsely pubescent with spreading, brown, erect hairs, margins overlapping, ciliate, auriculate, sheath blades broadly to narrowly triangular, boat-shaped, wavy, increasingly so in larger culms, appressed to lower sheaths, spreading away from culm in the upper ones; ligule 1-2 mm long, chartaceous, margins rounded to truncate, erose; blades commonly up to 9 (-13) cm long, up to 1.5 (-2) cm wide, usually glabrous or nearly so, rarely the lower surface sparsely to densely pilose.  Inflorescences racemose, enclosed within numerous bracts on short branches; spikelets enclosed in a narrowly ovate, glabrous, many-nerved, ciliate-margined bract, linear, up to 30 mm long, chartaceous to indurate, florets 2, first floret perfect, sessile, second floret sterile, pedicellate; glumes chartaceous, linear to narrowly ovate, 15-230 mm long, scabrous toward base, becoming more densely pilose toward summit, many-nerved, rounded on the back, apex acuminate, awned, the awn 1-1.5 mm long; first lemma chartaceous, linear, 2.7-3 mm long, evenly appressed pubescent, evenly to densely long-pilose toward summit, many-nerved, rounded on the back near base, keeled toward apex, apex long-acuminate, awned; first palea narrowly ovate, ca. 1.3 mm long, longitudinally grooved on abaxial margin where it comes in contact with the sterile, pedicellate floret, many-nerved, densely appressed pilose, margins inrolled slightly, apex long-acuminate, minutely bifid.  Caryopsis not seen"  (Wagner et al., 1999; p. 1582).

Description from GrassBase. In Hawai‘i, "spreading by rhizomes and forming extensive, dense stands on moist, shaded slopes and stream banks, 0-400 m" (Wagner et al., 1999; p. 1582); "occurs in extensive monotypic infestations in moist to wet areas.  Displaces native vegetation; virtually no other plants grow within black bamboo groves"  (Motooka et al., 2003). Rhizomes, discarded cuttings. China

"Cultivé/±envahissant"
Other species of Phyllostachys should also be avoided.

Physical:  "Does not invade grazed land, because cattle will graze the invading bamboo shoots, but animals cannot clear established stands.  Difficult to control.  Heavy equipment subject to damage by bamboo stems piercing radiators and hoses"  (Motooka et al., 2003).

Chemical: "Plant is sensitive to hexazinone and imazapyr and moderately sensitive to glyphosate. Foliar application difficult on tall plants. Most effective treatment requires mechanical clearing followed by herbicide treatment of re-sprouts. J. De Frank (Univ. Hawaii) recommended glyphosate plus fluazifop or imazapyr. Basal stem application of imazapyr looks promising" (Motooka et al., 2003).
