[A]rcheophytes are adapted to habitat types created early in history, including pastures, fields, and their edges; many of the neophytes, on the other hand, occur predominantly in ruderal, industrial, and urban habitats. […] [T]he proportion of neophytes is much higher in the flora of Berlin than in adjacent non-urban areas, but no difference was found for archeophytes.

The separation between natives and archeophytes relies on a combination of paleobotanical, archeological, ecological, and historical evidence (archeophytes and neophytes are absent from the fossil record in the last glacial period, the late glacial, and the early post-glacial). Archeophytes are often known from archeological evidence to have been present in prehistoric times.

As a consequence of the human displacements which occurred in Southern Europe from the East to the West, archeophytes (i.e. the exotic species that were introduced before 1500) were established in Western European territories such as the Iberian peninsula.
