Juniperus scopulorum 'Moonglow' / Moonglow Rocky Mountain juniper

Juniperus scopulorum 'Moonglow' is a relatively narrow, upright-pyramidal selection of Rocky Mountain juniper with exceptionally showy, silvery Blue foliage. Although narrow, it is broader than Juniperus scopulorum 'Skyrocket,' a similar cultivar. After 10 years of growth, a mature specimen will measure 20 feet (6 m) tall and 8 feet (2.5 m) wide, an annual growth rate in excess of 2 feet (60 cm).

According to Monrovia Nursery, "give this robust gray Juniper lots of space. It is a rugged and reliable plant for large-scale screening, massive hedges and windbreaks. Also works well as a single specimen in lawns or in conjunction with other ground covers. Use it as a corner element street-side or to interrupt long fence lines. Include a topiary form of this plant in a porch or entryway container planting. As its name suggests, the silver-gray foliage will reflect light under strong moonlight."

This cultivar originated as a seedling selected in the 1970s by Hillside Nursery, Lehighton, Pennsylvania. Currently Monrovia Nursery of Azusa, California is actively producing and marketing it.
