##### Alternative Names

cedar tree, juniper, juniper bush, savin, evergreen, cedar apple, Rocky
Mountain cedar

##### Uses

*Ethnobotanic*: Rocky Mountain juniper was and still is used by many
tribes for incense in purification and ritual (Kindscher 1992). The
Blackfeet made a tea from the berries of the Rocky Mountain juniper to
stop vomiting (Kindscher 1992). A Blackfeet remedy for arthritis and
rheumatism was to boil juniper leaves in water, add one-half teaspoon of
turpentine, and when cooled, rub the mixture on affected parts. The
Blackfeet also drank a tea made from *Juniperus scopulorum* root as a
general tonic; mixed with *Populus* leaves this root tea became a
liniment for stiff back or backaches (M^c^Clintock 1909, Johnston 1970,
Hellson 1974).

The Cheyennes steeped the leaves of the Rocky Mountain juniper and drank
the resulting tea to relieve persistent coughing or a tickling in the
throat. It was also believed to produce sedative effects that were
especially useful for calming a hyperactive person. Cheyenne women drank
juniper tea to speed delivery during childbirth (Grinnell 1962). The
Cheyenne, along with the Flathead, Nez Perce, Kutenai, and Sioux, made a
tea from juniper boughs, branches, and fleshy cones. The tea was used as
a cure for colds, fevers, tonsillitis, and pneumonia (Hart 1976).

As a cure for asthma, the Gros Ventres ate whole juniper berries or
pulverized them and boiled them to make a tea. They also made a
preparation from the leaves mixed with the root, which they applied
topically to control bleeding (Kroeber 1908). The Crow drank this
medicinal tea to check diarrhea and to stop lung or nasal hemorrhage.
Crow women drank it after childbirth for cleansing and healing (Hart
1976).

The wood of red cedar is very durable, and is used for lance shafts,
bows, and other items. Flutes made from juniper wood were highly
regarded by the Cheyenne.

*Ornamental*: All of the native junipers are valuable ornamental
species, and many horticultural varieties have been developed. Rocky
Mountain juniper is widely used in shelterbelts and wildlife plantings.
The close-grained, aromatic, and durable wood of junipers is used for
furniture, interior paneling, novelties, and fence posts. The fruits and
young branches contain aromatic oil that is used in medicines.

*Wildlife*: Junipers are important to wildlife throughout the country.
Their twigs and foliage are eaten extensively by hoofed browsers, but
the chief attraction to wildlife is the bluish-black berry-like fruit.
The cedar waxwing is one of the principal users of juniper berries, but
numerous other birds and mammals, both large and small, make these
fruits and important part of their diet. In addition to their wildlife
food value, junipers provide important protective and nesting cover.
Chipping sparrows, robins, song sparrows, and mockingbirds use these
trees as one of their favorite nesting sites. Juncos, myrtle warblers,
sparrows of various kinds, and other birds use the dense foliage as
roosting cover. In winter their dense protective shelter is especially
valuable.

##### 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 (M^c^Gregor 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

*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.
