Discussion | Saccharum officinarum is native to tropical Asia and the Pacific islands. It is cultivated for sugar production in various parts of the world, including Texas, Louisiana, and Florida. It is also becoming popular as an ornamental plant for gardens in warmer parts of the contiguous United States, and appears to be established in some parts of the southeastern United States. A number of different, clonally propagated color forms are available. It hybridizes with S. spontaneum (see discussion above).
