Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Summary

Bloom Color: Green, Yellow. Form: Columnar, Oval, Pyramidal.


Physical Characteristics

 icon of manicon of cone
Juniperus virginiana is an evergreen Tree growing to 20 m (65ft) by 8 m (26ft) at a slow rate.
It is hardy to zone (UK) 4. It is in leaf all year, in flower from April to May, and the seeds ripen in October. The species is dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). and is pollinated by Wind. The plant is not self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline soils.
It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought. The plant can tolerates strong winds but not maritime exposure.

Edible Uses

Edible Parts: Fruit
Edible Uses: Tea

Fruit - raw or cooked[106]. A sweetish resinous flesh[82]. They can be crushed and used as a flavouring in soups and stews[257]. The cones are about 5mm in diameter[200]. About 10mm according to another report[226]. A tea is made from the fruit[159]. It is not very nice[159]. It is made from the young branchlets and the fruit according to one report[183].

Abortifacient  Anthelmintic  Antiseptic  Aromatherapy  Cancer  Diaphoretic  Diuretic  Emmenagogue  
Rubefacient  Stimulant

Pencil cedar leaves were much used medicinally by the native N. American Indians, and also in folk medicine by the white settlers, especially to treat chest complaints and skin problems such as venereal warts and other excrescences[269]. The leaves are anthelmintic, diuretic, rubefacient and stimulant[4, 257]. A decoction has been used in the treatment of coughs and colds, general weakness and as a medicine for convalescents[257]. The berries are anthelmintic, diaphoretic, emmenagogue and mildly antiseptic[4, 213, 222, 257]. They have been chewed as a treatment for mouth ulcers[213, 257] or made into a tea to treat colds, rheumatism, worms etc[222, 257]. The fresh young twigs are used as a diuretic[213]. An infusion has been used both internally and as a steam bath in the treatment of rheumatism[257]. The essential oil from the wood is an abortifacient, in some cases it has caused vomiting, convulsions, coma and death[4, 213]. The plant is said to contain the anticancer compound podophyllotoxin[222]. The essential oil from the berries is used in aromatherapy. Its keyword is 'Composing'[210].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Essential  Incense  Insecticide  Repellent  Shelterbelt  Tinder  Wood

An essential oil is obtained from the wood[1, 46, 57, 61]. Composed of cedar camphor or cedrol[213], it is used in soaps, as an insecticide and moth repellent[61, 213], a deodorant, in polishes, perfumery etc[4, 21]. Chips of the wood have been used as moth repellents[269]. The leaves are used as an incense[46, 213] and are also either burnt or crushed and then scattered around as an insect repellent[169, 257]. The crushed bark can be used as a soft base in cradles[257]. The bark has also been cut into strips and used to make mats[257, 269]. The red inner bark is a source of a red dye[269]. The bark of the tree is useful as tinder in starting fires Boy Scout style[269]. Some cultivars of this tree are suitable for ground cover when spaced about 90cm apart each way[208]. 'Tripartita' and 'Chamberlaynii' have been recommended[208]. A fairly wind resistant tree, it can be grown as part of a shelterbelt planting[200]. Wood - very durable, light, brittle, soft, easily worked, very fragrant, insect-resistant[1, 46, 82, 171, 227]. The wood does not shrink much on drying and weighs 30lb per cubic foot[227]. The reddish wood is highly prized for cabinet making[226], it is also used for fencing, the casing of lead pencils etc[1, 46, 82, 171].

Cultivation details

Landscape Uses:Christmas tree, Firewood, Screen, Seashore, Specimen, Street tree. Succeeds in most soils if they are well drained, preferring a neutral or slightly alkaline soil[1, 11] and succeeding on chalk[200]. Established plants are drought tolerant, succeeding in hot dry positions[200]. They are also fairly wind-resistant[200]. A very ornamental and hardy plant[1]. It is very slow growing[4] and apparently short-lived in Britain[185], though it is very long-lived in its native environment[226]. Another report says that plants live to a moderate age of 200 - 350 years in the wild[229]. Cultivated as a timber tree in some parts of C. and S. Europe[50] and used as a Christmas tree in parts of N. America[269], there are some named forms, selected for their ornamental value[200]. Closely related to J. scopulorum, it hybridizes with that species where their ranges overlap[226]. The main difference between the two species is that the fruits of this plant mature in one year whilst those of J. scopulorum take two years[226]. This species often hybridizes with other members of the genus. The crushed foliage has an aroma like soap or paint[185]. Plants are resistant to honey fungus[88]. In America this tree is a host of a gall-like rust that at certain stages in its life-cycle also attacks the leaves of apple trees[149]. Plants are usually dioecious, though trees with both male and female flowers are occasionally found[229]. Male and female plants must usually be grown if seed is required. Special Features: Attracts birds, North American native, Fragrant foliage, Attracts butterflies, Attractive flowers or blooms.

Propagation

The seed requires a period of cold stratification. The seed has a hard seedcoat and can be very slow to germinate, requiring a cold period followed by a warm period and then another cold spell, each of 2 - 3 months duration[78, 81]. Soaking the seed for 3 - 6 seconds in boiling water may speed up the germination process[11]. The seed is best sown as soon as it is ripe in a cold frame. Some might germinate in the following spring, though most will take another year. Another possibility is to harvest the seed 'green' (when the embryo has fully formed but before the seedcoat has hardened). The seedlings can be potted up into individual pots when they are large enough to handle. Grow on in pots until large enough, then plant out in early summer. When stored dry, the seed can remain viable for several years[1]. Cuttings of mature wood, 5 - 10cm with a heel, September/October in a cold frame. Plant out in the following autumn[1, 78]. Layering in September/October. Takes 12 months[78].

the berries if dried properly can be used like other juniper berries, but in 1/2 amounts. they are not toxic if consumed this way, as noted in your footnotes.
