The Cologreen Rocky Mountain Juniper, also known as the Colorado Green Juniper, is a dense and narrowly columnar evergreen shrub with soft textured silvery-gray needle-like foliage and abundant small blue berries. This is a great choice for narrow spaces, landscape accents, privacy screens, and difficult landscape situations. This tree has dark green foliage which remains dark green throughout the winter. Neither the flowers nor the fruit is ornamentally significant.
The Cologreen Juniper is a dense multi-stemmed evergreen shrub with a shapely oval form. This is a relatively low maintenance shrub, however, if pruning is wanted it should be done in late winter once the threat of extreme cold (or heat) has passed. This is an ArborAdvisor recommendation due to its adaptability, low maintenance, and cold and drought tolerance.
The Cologreen Juniper will grow to be about 15 feet tall at maturity, with a width of 6 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 60 years or more.
This shrub should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a native North American juniper species.
