Cologreen Juniper Tree

Juniperus scopulorum 'Cologreen' is an upright, narrow-conical evergreen with dense, bright-green foliage. It provides a compact vertical accent while retaining the characteristic evergreen structure of Rocky Mountain juniper. ## Form and landscape use Cornell University’s [cultivar record](https://woodyplants.cals.cornell.edu/cultivar/11200) describes a dense, compact, cone-like plant reaching 15–20 feet tall and about 6 feet wide, with tightly knit foliage. Oregon State University also lists 'Cologreen' as an upright, narrow cultivar with green foliage in its [Rocky Mountain juniper profile](https://landscapeplants.oregonstate.edu/plants/juniperus-scopulorum). Its narrow outline suits a specimen planting or a vertical element in a screen, provided the site can accommodate its mature height. ## Growing conditions Choose a sunny location with well-drained soil. The cultivar record lists hardiness to USDA zone 3; the species profile notes that Rocky Mountain juniper withstands drought. Water during establishment, then avoid keeping the root zone persistently wet. ## Maintenance Give the plant room to develop its natural conical outline. Remove dead or damaged branches as needed; routine shearing is unnecessary for a healthy, naturally narrow specimen.
