The Blue Arrow, on the other hand, requires almost no annual pruning. If you aim to make it into a hedge, you will not achieve a beautiful result despite the amount of work you will have to do. It follows that the Skyrocket will have a pyramidal shape, and to keep it columnar, you will have to cut it regularly. It will start to expand and become 3-4 and even 5 feet wide, closer to ten years old.Īt the same time, the Blue Arrow will have a slender shape throughout its life. In the first few years, Skyrocket is narrow and columnar. After ten years of growth, they will reach 13-15 feet but will end up about 20 feet tall.

Northwest Trees: Identifying & Understanding the Region's Native Trees (field guide ed.). The tree is sometimes planted as a windbreak and horticulturally in rocky, poorly irrigated soils. The dried berries can be roasted and ground into a coffee substitute. Ī small quantity of ripe berries can be eaten as an emergency food or as a sage-like seasoning for meat. Among many Native American cultures, the smoke of the burning cedar is used to drive away evil spirits prior to conducting a ceremony, such as a healing ceremony. The cones were also sometimes boiled into a drink used as a laxative and to treat colds. Some Plateau Indian tribes boiled an infusion from the leaves and inner bark to treat coughs and fevers. According to one study, a single bird consumed 900 in five hours. It requires about 25 centimetres ( 9 + 7⁄ 8 in) of annual precipitation. It grows at altitudes of 500–2,700 m (1,600–8,900 ft) on dry soils, often together with other juniper species. The species is native to western North America, in Canada in south British Columbia and southwest Alberta, in the United States sporadically from Washington east to North Dakota, south to Arizona and also locally western Texas, and northernmost Mexico from Sonora east to Coahuila. It is a cryptic species barely distinguishable on morphology, though it does differ in phenology, with the cones maturing in 14–16 months, and often has the tips of the seeds exposed at the cone apex. scopulorum, it has recently been shown to be genetically distinct, and has been described as a new species J. maritima. In both locales, there are a considerable number of young and old specimens. Isolated populations of junipers occur close to sea level in the Puget Sound area in Washington Park near Anacortes and southwestern British Columbia in a park called Smugglers Cove. virginiana, and often hybridizes with it where their ranges meet on the Great Plains. Juniperus scopulorum is closely related to J. One particular individual, the Jardine Juniper in Utah, is thought to be over 1,500 years old, while a dead trunk found in New Mexico was found to have 1,888 rings older trees in the same area are suspected to exceed 2,000 years. Limb essential oil is primarily α-pinene and leaf essential oil is primarily sabinene. Essential oil extracted from the trunk is prominent in cis-thujopsene, α-pinene, cedrol, allo-aromadendrene epoxide, (E)-caryophyllene, and widdrol. Rocky Mountain juniper is an aromatic plant. It is dioecious, producing cones of only one sex on each tree. The pollen cones are 2–4 mm ( 3⁄ 32– 5⁄ 32 in) long, and shed their pollen in early spring. The seed cones are berry-like, globose to bilobed, 5–9 mm ( 3⁄ 16– 11⁄ 32 in) in diameter, dark blue with a pale blue-white waxy bloom, and contain two seeds (rarely one or three) they are mature in about 18 months and are eaten by wildlife. The juvenile leaves (on young seedlings only) are needle-like, 5–10 mm long. The leaves are arranged in opposite decussate pairs, or occasionally in whorls of three the adult leaves are scale-like, 1–3 mm long (to 5 mm on lead shoots) and 1–1.5 mm ( 1⁄ 32– 1⁄ 16 in) broad. The shoots are slender, 0.7–1.2 millimetres ( 1⁄ 32– 1⁄ 16 in) diameter. Juniperus scopulorum is a small evergreen conifer reaching 5–15 metres (16–49 feet), rarely to 20 m, tall, with a trunk up to 1 m (3 ft 3 in), rarely 2 m, in diameter.
