Discussion

The name Juniperus mexicana Sprengel has been misapplied to this species. Reports of hybridization with J. virginiana and J. pinchotii have been refuted using numerous chemical and morphologic characters (R. P. Adams 1977).

Ashe juniper is a source of Texas-cedarwood oil and fence posts.
