Redwing (Heteropterys brachiata) is an invasive vine in Hawaii and Florida. It is native to Central and South America. Using other trees as support, this shade-tolerant plant grows above them while smothering the host species. It produces many winged seeds (samaras) adapted to wind dispersal. Not much is officially documented about this species, as it is somewhat rare in cultivation. Because of that, it scores on the lower end of the high-risk rating. For instance, how many seeds are produced from one plant is unknown. However, BIISC crew found 100’s of seedlings sprouting in the areas surrounding naturalized populations. The rating will increase when more ecological information becomes available, perhaps dramatically. Prevention is best with invasive plants, redwing vine should be avoided!
