Rye generally resembles wheat (genus Triticum) or barley (genus Hordeum) and is apparently frequent as a waif/escape. Since it is planted for roadside stabilization and as a cereal crop, it is likely to turn up almost anywhere. However, it is unlikely that any populations have become truly established and self-reproducing, per Vascular Plants of North Carolina.
An important crop, cultivated for at least 8000 years, per Weakley's Flora (2023).
