Discussion

By the nineteenth century, Rosa laevigata was widely found in the southern United States as a hedging shrub, being commonly distributed by stem cuttings and rhizomes, representing relatively few clones (C. A. Walker 1996; Walker and D. J. Werner 1997). The species was named and described from plants collected in Georgia in the 1790s by A. Michaux, who was unaware that his newly discovered species was native to Asia. This suggests a very old introduction into the United States, where it occurs only in the southeast to eastern Texas and the Carolinas. Shrubs form dense, rhizomatous thickets with stems capable of climbing to 100 dm. Leaves are persistent and leathery with mostly three leaflets and stipules free for most of their lengths, then caducous. Inflorescences consist of one (rarely two) white-petaled flowers and have densely setose hypanthia and hips.

In China, where the species is considered one of the most beautiful and cherished of roses, Rosa laevigata has a long history of use by herbal practitioners to treat bronchitis, dysentery, and urogenital disorders, and to restore hair color (J. A. Duke and E. S. Ayensu 1985, vol. 2).
