Herbertia lahue is probably introduced in Florida.

The taxonomy of Herbertia lahue has been much confused. Plants from North America were originally treated as H. caerulea, separate from the South American members of the genus. P. Ravenna (1968) regarded differences between this and two South American species, H. lahue and H. amoena, as trivial and not sufficient to allow anything more than infraspecific separation. He considered plants from northern Argentina to be indistinguishable from those from North America and united them under subsp. caerulea. Without ennumerating their differences, Ravenna treated plants from coastal southern Brazil, Uruguay, and Argentina with slightly smaller flowers as subsp. amoena (Grisebach) Goldblatt, and those from Chile as subsp. lahue. The variation in North American populations makes it impossible to maintain even subspecies in H. lahue on the basis of available information.
