Notes:
André Michaux described Rosa laevigata in Flora Boreali-Americana (1803) from specimens located in the Southern state of Georgia in the USA. The same rose, from China, had been given the name Rosa sinica earlier, in 1789, and was described as in cultivation in 1759. But because the same name, R. sinica, was also used by Linneaus to describe the China rose Rosa chinensis, the name was found to be invalid by Crépin under the rules of taxonomy.
Rosa laevigata Michaux is native to the sub-tropical parts of S.E. China and Vietnam, is naturalized over large areas in the American South, and is not reliably hardy in the USA below Zone 7. See References.
