Cassava is a woody perennial crop.The stem is erect, (wooden), reaching 2-5m in height, with alternate simple leaves that are palmately deeply divided, papery, and lanceolate-shaped.Unisexual flowers form (corymb-like inflorescence), (terminal), and are monoecious.Cassava was introduced to China in the 1820s, initially cultivated in Gaogou, Guangdong province. It was later introduced to Hainan Island and has since spread widely throughout southern China, with the most cultivation occurring in Guangxi, Guangdong, and Hainan. Fujian, Yunnan, Jiangxi, Sichuan, and Guizhou provinces in the south also have trial plantings.
