Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Juniperus scopulorum Common Name: Rocky Mountain juniper Family: Cupressaceae Author: Sarg. Known Hazards: None known Mature Height: 10 Mature Width: 4 Habitat: Scattered singly on dry rocky ridges, foothills and bluffs[82, 85] in montane areas or in dry habitats of the coastal forest region[226]. The best specimens are found on slightly alkaline soils[229].
Cultivation Notes: Succeeds in most soils, including chalk[200], so long as they are well drained, preferring a neutral or slightly alkaline soil[1, 11]. A drought tolerant species once established, succeeding in hot dry positions[200]. Plants are fairly wind-resistant[200].
A long-lived but slow-growing tree in its native range[227], it is very slow growing in Britain where it only makes a shrub[185].
Closely allied to J. virginiana[1, 81] and hybridising with it where the ranges meet[226]. It differs mainly in the fruit, which takes two years to mature in this species instead of one[226].
Plants are resistant to honey fungus[88]. This tree is apparently resistant to the rust fungus that attacks the closely related J. virginiana[149].
Dioecious. Male and female plants must be grown if seed is required.
