Juniperus deppeana (Alligator juniper)
Flaigg, Norman G.

Juniperus deppeana Steud.

Alligator juniper

Cupressaceae (Cypress Family)

USDA Symbol: JUDE2

USDA Native Status: Native to U.S.

Alligator juniper forms a broadly-pyramidal or round-topped crown. The distinctive bark is furrowed into checkered plates. Fragrant, dark blue-green, scale-like foliage and copper-colored fruit are other landscape characteristics. This evergreen grows to 48 ft. in height.

Alligator Juniper is easily recognized by its distinctive bark. One of the largest junipers, it is used for fuel and fenceposts. New sprouts often appear at the base of cut stumps. The large berries are consumed by birds and mammals. Large trees often have a partially dead crown of grotesque appearance with some branches that die and turn light gray instead of falling; other branches die only in a vertical strip and continue to grow on the other side.
