Discussion
Gynura aurantiaca is a tender pot-plant that is sometimes grown outdoors. It is marginally established in the flora, persisting as an escape from cultivation in southern Florida. It may be encountered elsewhere along the Gulf Coast. The orange, filiform appendages of the style branches are distinctive; the flowers are reported to be unpleasantly scented.
Selected References
None.
