    Junipers are coniferous plants in the genus Juniperus/dunprs/*[1] of the cypress family Cupressaceae.Depending on taxonomic viewpoint, between 50 and 67species of juniper are widely distributed throughout theNorthern Hemisphere, from the Arctic, south to tropicalAfrica in the Old World, and to the mountains of CentralAmerica.

    1 DescriptionFor more details on this topic, see Juniper berry.Junipers vary in size and shape from tall trees, 2040

    Cones and leaves of Juniperus communis

    m (66131 ft) tall, to columnar or low spreading shrubswith long trailing branches. They are evergreen withneedle-like and/or scale-like leaves. They can be eithermonoecious or dioecious. The female seed cones are verydistinctive, with eshy, fruit-like coalescing scales whichfuse together to form aberry"-like structure, 427 mm(0.161.06 in) long, with 112 unwinged, hard-shelledseeds. In some species these berriesare red-brownor orange but in most they are blue; they are often aro-matic and can be used as a spice. The seed maturationtime varies between species from 618 months after pol-lination. The male cones are similar to those of otherCupressaceae, with 620 scales; most shed their pollenin early spring, but some species pollinate in the autumn.Many junipers (e.g. J. chinensis, J. virginiana) have twotypes of leaves: seedlings and some twigs of older treeshave needle-like leaves 525 mm (0.200.98 in) long;and the leaves on mature plants are (mostly) tiny (24mm (0.0790.157 in)), overlapping and scale-like. Whenjuvenile foliage occurs on mature plants, it is most often

    2 Classication

    Juniper needles, magnied. Left, Juniperus communis(Juniperus sect. Juniperus; note needles 'jointed' at base). Right,Juniperus chinensis (Juniperus sect. Sabina; note needles merg-ing smoothly with the stem, not jointed at base).

    Juniperus phoenicea on El Hierro, Canary Islands

    An Eastern Juniper in October laden with ripe cones.

    The number of juniper species is in dispute, with two re-cent studies giving very dierent totals, Farjon (2001)accepting 52 species, and Adams (2004) accepting 67species. The junipers are divided into several sections,though (particularly among the scale-leaved species)

    Cones and seeds.

    3 Cultivation and usesJuniper berries are a spice used in a wide variety of culi-nary dishes and best known for the primary avoring ingin (and responsible for gin's name, which is a shorteningof the Dutch word for juniper, genever). Juniper berriesare also used as the primary avor in the liquor Jeneverand sahti-style of beers. Juniper berry sauce is often apopular avoring choice for quail, pheasant, veal, rabbit,venison and other meat dishes.Many of the earliest prehistoric people lived in or near ju-niper forests which furnished them food, fuel, and woodfor shelter or utensils. Many species, such as J. chinen-sis (Chinese Juniper) from eastern Asia, are extensivelyused in landscaping and horticulture, and as one of themost popular species for use in bonsai. It is also a symbolof longevity, strength, athleticism, and fertility.Some junipers are susceptible to Gymnosporangium rustdisease, and can be a serious problem for those peoplegrowing apple trees, the alternate host of the disease.Some junipers are given the common namecedar,in-cluding Juniperus virginiana, thered cedarthat is usedwidely in cedar drawers.Eastern redcedaris the cor-rect name for J. virginiana. The lack of space betweenthe wordsredandcedarindicate that this speciesis not a true cedar, Cedrus.

    Juniper (Juniperus osteosperma and scopulorum) essential oil

    In Morocco, the tar (gitran) of the arar tree (Juniperusphoenicea) is applied in dotted patterns on bisque drink-ing cups. Gitran makes the water more fragrant and issaid to be good for the teeth.Some Indigenous peoples, such as the Dineh, have tradi-tionally used juniper to treat diabetes.*[3] Animal stud-ies have shown that treatment with juniper may re-tard the development of streptozotocin-induced diabetesin mice.*[4] Native Americans have also used juniperberries as a female contraceptive.*[5] The 17th Centuryherbalist physician Nicholas Culpeper recommended theripened berries for conditions such as asthma and sciatica,as well as to speed childbirth.*[6]Juniper is one of the plants used in Scottish and GaelicPolytheist saining rites, such as those performed atHogmanay (New Year), where the smoke of burning ju-niper is used to cleanse, bless and protect the householdand its inhabitants.*[7]*[8]*[9]Juniper berries are steam distilled to produce an essentialoil that may vary from colorless to yellow or pale green.Some of its chemical components are alpha pinene,cadinene, camphene and terpineol. Leaves and twigs ofJuniperus virginiana are steam distilled to produce oil ofjuniper. Middle Tennessee and adjacent northern Al-abama and southern Kentucky are the centers for this ac-tivity. The U.S. Forest Service has provided plans for theapparatus required. This work is typically done during

  • 5periods of cold weather to reduce the loss of essential oilto evaporation, which is greater in warmer weather, andto take advantage of a time of year when labor might bemore readily available.Juniper in weave is a traditional cladding technique usedin Northern Europe, e.g. at Havr, Norway.*[10]
