#Dlium Petung or bamboo betung or dragon bamboo or giant bamboo (Dendrocalamus asper) is a species of plant in the Poaceae, large and strong stems, high adaptability, used as building material and structural wood for construction and cooked shoots for vegetables.
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.
This species grows best at elevations of 400-500 meters, although it is capable of growing at elevations of up to 1900 meters. 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.

Damn... this channel is an absolute gem... literally any plant I search... i find there's a video already made... keep up ur good work whoever you are...
How can I propagate this variety of bamboo?Through seeds or shoot.From where and how can they be procured.Please give your suggestion.
Can anyone help?
This is available in India. I know we have these in Kerala. I don't know what to use to propagate. Probably seeds.
How fast do they grow? I have a plan for build a small bamboo bespoke, bamboo hut, small bamboo house, just 2 bedrooms. Is 1 years enough? Or 2 years to harvest and reach maturity?
30/40cm per day with much water but depends what species
How old is it?
ONE THOUSAND YEARS OLD AHAHHAHAHAHA IM EVILLLL

I hope it will remain sustainable, even though price of wood in future will become more expensive and luxurious
