Discussion
R. E. Woodson Jr. (1936b) surmised Trachelospermum jasminoides to be native to southeastern China and to have spread elsewhere in Asia through cultivation and escape. Although T. jasminoides is widely cultivated in warmer parts of the United States, only two collections have been seen that appear to represent naturalized specimens, both from disturbed woodland habitats.
