Discussion | Native to central South America, Araujia odorata was introduced to the United States as an ornamental in the 1930s and first observed in a citrus grove in Florida in 1957 (D. P. H. Tucker and R. L. Phillips 1974; D. L. Spellman and C. R. Gunn 1976). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The naturalization of Araujia sericifera in the flora area has been substantiated only for Arizona and California, although it has also been reported for Georgia (J. T. Kartesz, http://www.bonap.org/MapSwitchboard.html). A recent risk assessment estimates that about one-third of the United States presents suitable habitat for the species (Animal and Plant Health Inspection Service [U.S.D.A.] 2012).
