About
Rosa bracteata, commonly known as the Macartney rose, is a species of rose native to southern China and Taiwan that has become invasive in parts of the United States following its introduction as an ornamental plant. It is the only wild species in the section Bracteatae of the genus Rosa. In 2026, a chromosome-scale genome assembly of Rosa bracteata was published, providing a genomic resource for rose evolution and breeding studies.
Where it grows
Rosa bracteata is a highly adaptable plant and can grow in highly disturbed areas. It can be found in areas ranging from pastures, rangeland, drainage ditches, and along roadsides and fence lines. R. bracteata tends to prefer dark, waterlogged, and clay-based soil compositions. This species was introduced into the United States from Asia, and is only found within the lower 48 states, mostly in the southeastern United States. Some of the states it can be found in include Texas, Louisiana, Arkansas, Mississippi, Alabama, Georgia, Florida, South Carolina, North Carolina, Tennessee, Kentucky, Virginia, and Maryland.
