Bambusa oldhamii, known as giant timber bambooorOldham's bamboo, is a large species of bamboo. It is the most common and widely grown bamboo in the United States and has been introduced into cultivation around the world. It is densely foliated, growing up to 20 metres (65 feet) tall in good conditions, and can have a diameter of up to 10 centimetres (4 inches).

Bambusa oldhamii grows to 17–20 m (56–66 ft) in height, with green culms reaching a maximum of 10 cm (4 in) in diameter.[2] Shoots grow rapidly in warmer months. The branches are short and leaves long.[3]
It was first described by Munro in 1868, the type specimen collected in Taiwan by Oldham (after whom the species was named). It is grouped in the subgenus Dendrocalamopsis. Dendrocalamus latiflorus is a misapplied name, under which it has been sold in the United States. It has also been confused with the related species B. atrovirensofZhejiang in mainland China.[2]
B. oldhamii is native to the island of Taiwan and to southern China (Fujian, Guangdong, Guangxi, Hainan, Zhejiang). It is widely cultivated and has become naturalized in several places (Ryukyu Islands, New Zealand, Chiapas, Honduras, Peru, etc.)[1][4][5][6][7][8][9][10]
It has been introduced into cultivation around the world; it is grown under glass in Germany,[2] and in Australia, Puerto Rico, Florida, Texas, Tennessee, Maryland, Virginia, North Carolina, South Carolina, Oklahoma, Kentucky, Georgia, Alabama, Arkansas, Mississippi, Arizona, Nevada, Hawaii, Louisiana, and California, where it is the most common clumping bamboo grown.[2] The maximum height in cultivation varies with the temperature. It tolerates temperatures down to -7 °C (20 °F).[3]
InTaiwan and China, the young shootsofB. oldhamii are highly sought after due to their crisp texture and sweet taste.[11] Cultivation in Taiwan has declined with many stands of bamboo converted to pineapple production, a number of subsidy and support programs have been established as the cultivated bamboo groves provide valuable wildlife habitat and their destruction challenges the endangered farmland green tree frog.[12]
The culms are used for furniture making, but are not suited to construction.[3]
