Did you know?
Even though the species name vulpina means fox, fox grape is the name more commonly associated with Vitis labrusca. Evidently, this name came from the fact that foxes were attracted to the grapevines. Winter grape, and another common name, frost grape, refer to the fact that the tart fruits become sweeter after the first frost, not because it grows better where the winters are colder (Wikipedia contributors). In fact it‘s just the opposite as this species is more common farther south.

State Ranking Justification [-]
There are six verified occurrences, but the species remains under-surveyed so more may be found.
