Description

General: Cypress Family (Cupressaceae). Rocky Mountain cedar (Juniperus scopulorum ) is a medium sized dioecious or rarely monoecious tree from 10-20 m (33-66') tall (McGregor et al. 1986, Stephens 1973). The evergreen tree is scraggly with rounded crown to pyramidal. The bark is dark reddish-brown to grayish in color, thin, fibrous, and usually shreds with age. Leaves are green or blue-green, usually barely overlapping and closely appressed, scalelike and 0.2-0.3 cm (1/16-1/8") long or needlelike and 0.6-1.2 cm (1/4-1/2") long. Recessed glands occur on the dorsal side of the leaves. Juniperus scopulorum differs from red cedar (J. virginiana) by the blunt leaves, the leaves not overlapping, and the longer, elliptic glands. The fruits of J. scopulorum mature in the second season, while in J. virginiana fruits mature in the first season. Juniperus scopulorum is usually a more rounded tree and J. virginiana is more conical. Male and female cones are on separate trees. The staminate (male) cones are yellowish-brown, papery, solitary at the tips of branchlets, ovoid to ellipsoid, and 0.2-0.4 cm (1/16-1/8") long. The ovulate (female) cones are solitary at the tips of branchlets, dark blue or bluish-purple, waxy and berry-like, and 0.4-0.7 cm (3/16-1/4") long. The female cones ripen from September through October. There are 1-3 seeds per cone, yellow-brown and round, 2-4 mm in diameter, ridged near the base and sometimes shallowly pitted.

Distribution

Rocky Mountain juniper grows in prairie hillsides, fields, pastures, and occasionally in woodlands, in rocky, sandy, or clay soils. The distribution of Rocky Mountain juniper is from British Columbia and Alberta south through the Great Basin and the Rocky Mountains to Arizona and New Mexico and into western Texas, north across eastern Colorado, western Nebraska to western North Dakota, and west in Montana. The range overlaps that of Juniperus virginiana only in North Dakota.

Establishment

Rocky Mountain juniper is often used as an ornamental because of its evergreen foliage. Juniper can be easily transplanted in the early spring before it starts its new growth. It is especially well adapted to dry areas. The junipers are generally propagated by cuttings. Propagation from Cuttings Cuttings are made 5 to 15 cm (2 to 65 inches) long from new lateral growth tips stripped of older branches. A small piece of old wood, a “heel,” is thus left attached to the base of the cutting. Some propagators believe this to be advantageous. In other cases, good results are obtained when the cuttings are just clipped without the “heel” from the older wood. Cuttings from the current season’s terminal growth also root well. Cuttings to be rooted in the greenhouse can be taken at any time during the winter or rooted outdoors on heated beds. Exposing the stock plants to several hard freezes seems to give better rooting. Optimum time for taking cuttings is when stock plants have ceased growth (i.e. the late fall-winter propagation period is more successful than summer). For propagating in an outdoor cold frame, cuttings are taken in late summer or early fall. There may be advantages to using bottom heat. Lightly wounding the base of the cuttings is sometimes helpful, and the use of root-promoting chemicals, especially IBA, is beneficial. Recommendations for root-promoting chemicals include the following: 2500 IBA Quick-dip (Alabama), 3000 – 8000 ppm IBA liquid, and 0.3-4.5 percent IBA talc. A medium-coarse sand or a 10:1 mixture of perlite and peat moss is a satisfactory rooting medium. Maintenance of a humid environment without excessive wetting of the cuttings is desirable, as is a relatively high light intensity. A light, intermittent mist can be used. Bottom heat of 60-65°F (12°C) is critical the first six weeks of propagation to allow the basal wound of cuttings to callus.

Seed Propagation

Propagation

Propagation

Juniperus scopulorum flowers from April to June. The fruits should be gathered in the fall (September-October) as soon as the berry-like cones become ripe. Rocky Mountain juniper trees come to seed-bearing age in 10-20 years, and they bear cones every 2-5 years. Seed collection can be done by stripping or picking the berries by hand from the trees, or by flailing the fruits to ground cloths. Be careful to pick only ripe berries. Since the number of filled seeds varies widely from tree to tree, it is important to test the seeds by cutting to determine percent fill. Seeds may be stored as berries or cleaned seeds. The seeds can be recovered by macerating the fruits and floating the seeds to the top. The addition of detergent to the maceration water helps to separate seeds from the resinous fruits. Juniper seeds store quite well. They should be dried to 10-20% moisture and stored in a sealed container at cold temperatures. For best germination, seeds should be removed from the fruits, then the seed coat is softened by treating it with sulfuric acid for 120 minutes. After soaking the seeds in sulfuric acid, follow with 6 weeks of warm stratification at 20 to 30°C (70 to 85°F), or summer planting, then 10 weeks of pre-chilling at 4°C (40°F). Use of fresh seed reduced the warm stratification time. Rather than the acid treatment, two to three months of warm stratification could be used. As an alternative for cold stratification, the seed may be sown in the fall. Germination is delayed at temperatures above 15°C (60° F). Germination is often delayed in juniper seeds, as seeds are consistently highly dormant. Juniper seeds are usually sown in the nursery in the late summer or fall, but may be sown in spring or summer. The seeds of most species should be sown in fall to take advantage of natural pre-chilling. Juniper seeds are usually drilled in well-prepared seedbeds in rows 15 to 20 cm apart and covered with 0.6 cm of soil. In nurseries with severe climates, such as those in the Great Plains, considerable care must be taken to protect the beds with mulch and snow fences. Viability of the seed varies considerably from year to year and among lots, but it is never much over 50 percent. Treated seed is usually planted in the spring, either in outdoor beds or in flats in the greenhouse. Two or three years are required to produce plants large enough to graft. Juniperus scopulorum – 11-28 seeds per 110 kg fruit, 60 seeds per gram Extensive information about collecting and processing Rocky Mountain juniper seed can be found in Scianna (2000).

Management

The following information on the Traditional Resource Management (TRM) for Rocky Mountain juniper was provided by Lynn Youngbuck, who is Cherokee, Chiracahua, and Fox. TRM includes the following: • Take what you need, leaving the best to reproduce. • Speak to the plant, leave an offering of tobacco or sage before harvesting. The plant will grow back two stems for every one cut. • We humans are another strand in life. Plants sustain us and should be treated as another living being. • Plants were taken care of in extended family groups of women. They were taken care of and watched each year for generations. • Materials harvested were shared and traded with the whole tribe. Cultivars, Improved and Selected Materials (and area of origin) JUSC2 is readily available from nurseries throughout its range.
