The flowers of Hedychium coronarium are very fragrant. Naturalized populations have been reported several times from southern Louisiana, but the specimens I have seen are sterile and cannot be identified with certainty. There is also an old report from near Brunswick, Georgia (J. K. Small 1933, unpublished ms.), but I have seen no specimens from the state.
