Juniperus communis
Juniperus communis (Common Juniper)
Cupressaceae (Cypress Family)

Montane, sub-alpine. Woodlands, openings. Spring.
Madden Peak, June 22, 2004.

These Junipers, found in many northern countries of the world, creep low to the ground and spread to seven feet in diameter.  This specimen is growing right at tree-line and is only eight inches tall; those growing at lower altitude are commonly two-to-four feet high (but may be columnar trees to 18 feet tall).

In his Species Plantarum of 1753, Linnaeus named both the Juniperus genus and this species.

Colorado plant authority, William Weber, states that Juniperus communis is our only true Juniperus species; the other plants which we have been calling Juniperus should, according to Weber, be called Sabina. Most other botanists disagree and retain the Juniperus genus name.

See Juniperus osteosperma.
