American or Allegheny Pachysandra occurs sporadically in rich, rocky woodlands from Kentucky to Louisiana and Florida. The French plant explorer, André Michaux, discovered and named it by the late 1790s and John Fraser brought it into cultivation as early as 1800. Unlike its rambunctious Asian counterpart, the Allegheny Pachysandra is slow to spread. It is remarkably hardy, surviving winters as far north as Maine, but is not reliably evergreen above zone 6.
