D. asper grows in clumps, the shoots are purplish black and covered by blackish brown velvet. 20 meters high with curved ends, 40-50 cm long, 12-20 cm in diameter and 1-4 cm thick. Green or dark green or purplish green or whitish green or mottled white by lichen. The margins of the internodes are surrounded by hanging roots, the reed midrib 50x25 cm, covered by blackish brown velvet, the ears are rounded and sometimes curled to the base of the reed midrib leaf, 7 mm high with jute hairs up to 5 mm. Ligula serrated irregularly, 7-10 mm high with short bristles up to 3 mm. The leaves of the reed midrib are triangular with a narrowed base and bent back. Leaves on twigs with loose midrib or sparsely pale, without ears, ligular 2 mm, strands 15-45x1-8.5 cm, slightly hairy underside and short petioles. Flowers in panicles on leafless twigs with clusters of spikelets on each internode. The spikelets are ellipsoidal, 6-9x4-5 mm, flattened to the sides, have 1-2 gluma and 4-5 florets.

Average rainfall 2400 mm/yr, wide range of soil types but grows better in heavy, well-drained soils, full sun and minimum 25F temperatures. Thick reeds are very strong and durable. At a moisture content of 8%, the wood density is 0.7-0.8 g/cm³. At 15% water content, the fracture toughness is 103 N/mm², the compressive strength parallel to the fiber direction is 31 N/mm² and the shear strength is 7.3 N/mm². It is used for poles for houses, boat masts, shed frames, bridges, water pipes, musical instruments, furniture, household appliances, crafts, laminated boards, papier-mâché, chopsticks and toothpicks. Bamboo shoots have a large size and sweet taste.
