Noteworthy Characteristics

Juniperus ashei, commonly called Ashe juniper, is an evergreen large shrub or small tree that is primarily native to central Texas (Edwards Plateau section in particular), with additional populations found in Oklahoma (Arbuckle Mountains and Prior Creek), northern Arkansas, southern Missouri (limestone glades and bald knobs along bluffs of the White River and its tributaries) and northern Mexico. Typically matures to 15-25' tall with a rounded to flattened crown. Trunk usually branches near the base. Gray to reddish brown bark peels in strips. Scale-like green leaves retain good color in winter. Hemispheric raised abaxial glands on the leaves are distinctive. Trees are dioecious (separate male and female plants). Pollen cones on male trees are small and appear at the tips of the branchlets. Berry-like, bluish-purple fruiting cones (usually one seed per fruit) with a white waxy coating appear on female trees. Fruit is eaten by some birds and mammals.

Genus name comes from the Latin name for the juniper.

Specific epithet honors William Willard Ashe (1872-1932), forester with the U.S. Forest Service and plant collector.


No serious insect or disease problems. Junipers are generally susceptible to tip and needle blights. Cedar-apple rust and related rust diseases spend part of their life cycle on junipers. Root rot may occur, particularly in wet, poorly drained soils. Canker may attack bark or main stems. Occasional insect pests include aphids, bagworms, webworms and scale. Some people are allergic to pollen produced by male trees.
