Dendrocalamus latiflorus aka Giant Bamboo

Dendrocalamus latiflorus is an evergreen bamboo in the grass family, Poaceae. Its common names include sweet bamboo and Taiwan giant bamboo. Kew gives its native range as Assam to southern China and Taiwan. Other sources also record it in Myanmar and Vietnam. Growers across tropical Asia raise it for its young shoots. They also plant it for its looks.

This woody bamboo forms dense clumps rather than loose stands. Its upright culms bend down at the tips. Garden references give a height near 66 feet [20 metres]. A broader reported range reaches 46–82 feet [14–25 metres]. Clumps can spread to about 33 feet [10 metres]. Culm bases measure about 3–8 inches [8–20 centimetres] across. The plant keeps its leaves through the year. Wind carries pollen between its flowers.

Sweet bamboo grows fast in warm, wet climates. It suits subtropical sites and low to mid-elevation tropical land. In Taiwan, it grows up to 3,281 feet [1,000 metres] above sea level. Reports there record survival at temperatures down to −4°C. PFAF lists USDA zones 10–12. It needs an open site, since it does not grow in shade. Moist, fertile soil with good drainage gives the best growth. It can grow in sand, loam, or clay. Yet heavy clay and gravel reduce its value as a shoot crop. Acidic or alkaline soil also limits shoot production.

Plants raised from cuttings can form substantial clumps within three years. These may hold 20–25 culms, each 16–20 feet [5–6 metres] tall. Five-year plants may reach about 49 feet [15 metres]. Growers use culm or rhizome cuttings to raise new plants. Seed offers another route, but it is scarce and loses viability fast. Young plants may stay short for several years before making taller culms.

The young shoots and tender stems provide food, raw or cooked. Sources report a mild taste even before cooking. Growers may begin harvesting shoots in the second year. Processing includes steaming, cleaning, and boiling before eating or canning. Dried, shredded shoots also go into snacks. Mature culms supply material for baskets, pipes, small rafts, and buildings. They also provide pulp for paper. Leaves serve as packing and as material for hats and boat roofs. PFAF lists no known medicinal use. Both PFAF and Useful Tropical Plants report no known hazards. That does not establish safety for every use or for pets.
