Rocky Mountain Juniper

Scientific name

Juniperus scopulorum


The Rocky Mountain Juniper is a slow growing coniferous tree species that typically grows from 10-15 m tall. This species may also be known by the common names: Upright Juniper, Skyrocket Juniper, or Colorado/Western Red Cedar. The leaves are 1-2 mm long scales and are either light green or blueish gray coloured. The bark is reddish brown in colour and appears shedding. It flowers from April to May, developing cones that are oval shaped, 2-4 mm long, and appear at the tips of branches. These produce small, fleshy, light blue coloured berries with seeds. Rocky Mountain Juniper is a long-lived species that can survive 250-300 years. This plant is effective at controlling erosion and stabilizing steep shorelines.
