. The seed maturation time varies between species from 6 to 18 months after pollination. The male cones are similar to the other Cupressaceae, with 6 to 20 scales. In hardiness zones 7 through 10, junipers can bloom and release pollen several times each year. Different junipers bloom in autumn, while most pollinate from early winter until late spring. Jun chin close

Many junipers (e.g. '' J. chinensis'', '' J. virginiana'') have two types of leaves; seedlings and some twigs of older trees have needle-like leaves long, on mature plants the leaves are overlapping like (mostly) tiny scales, measuring . When juvenile foliage occurs on mature plants, it is most often found on shaded shoots, with adult foliage in full sunlight. Leaves on fast-growing 'whip' shoots are often intermediate between juvenile and adult. In some species (e.g. '' J. communis'', '' J. squamata''), all the foliage is of the juvenile needle-like type, with no scale leaves. In some of these (e.g. ''J. communis''), the needles are jointed at the base, while in others (e.g. ''J. squamata''), the needles merge smoothly with the stem. The needle leaves of junipers are hard and sharp, making the juvenile foliage very prickly to handle. This can be a valuable identification feature in seedlings, as the otherwise very similar juvenile foliage of cypresses ('' Cupressus,

s, which means they have seeds, but no flowers or fruits. Depending on the species, the seeds they produce take 1–3 years to develop. The impermeable coat of the seed keeps water from getting in and protects the embryo when dispersed. It can also result in a long dormancy that is usually broken by physically damaging the seed coat. Dispersal can occur from being swallowed whole by frugivores and mammals. The resistance of the seed coat allows it to be passed down through the digestive system without being destroyed along the way. These seeds last a long time, as they can be dispersed long distances over the course of a few years.

Classification

Sections

The genus has been divided into sections in somewhat different ways. A system based on molecular phylogenetic data from 2013 and earlier used three sections: * Section ''Caryocedrus'' – 1 species with large, blue, woody, 3-seeded cones; native to the Mediterranean * Section ''Juniperus'' – 14 species with blue or red seed cones, often with 3 seeds; 12 species native to the

''Sabina'' was further divided into clades.

Ecology

Juniper plants thrive in a variety of environments. The junipers from Lahaul valley can be found in dry, rocky locations planted in stony soils.

s where there are large, open spaces. Junipers are known to encompass open areas so that they have more exposure to rainfall. Decreases in fires and a lack of livestock grazing are the two major causes of western juniper takeover. This invasion of junipers is driving changes in the environment. For instance, the ecosystem for other species previously living in the environment and farm animals has been compromised. When junipers increase in population, there is a decrease in woody species like mountain big sagebrush and

. Among the juniper trees themselves, there is increased competition, which results in a decrease in berry production. Herbaceous cover decreases, and junipers are often mistaken for weeds. As a result, several farmers have thinned the juniper trees or removed them completely. However, this reduction did not result in any significant difference on wildlife survival. Some small mammals found it advantageous to have thinner juniper trees, while cutting down the entire tree was not favorable. Some junipers are susceptible to '' Gymnosporangium'' rust disease and can be a serious problem for those people growing

Toxicity

In drier areas, juniper pollen easily becomes airborne and can be inhaled into the lungs. This pollen can also irritate the skin and cause contact dermatitis. Cross-allergenic reactions are common between juniper pollen and the pollen of all species of cypress. Monoecious juniper plants are highly allergenic, with an Ogren Plant Allergy Scale (OPALS) rating of 9 out of 10. Completely male juniper plants have an OPALS rating of 10, and release abundant amounts of pollen. Conversely, all-female juniper plants have an OPALS rating of 1, and are considered "allergy-fighting".

General use

Juniper berries are a spice used in a wide variety of culinary dishes and are best known for the primary flavoring in gin (and responsible for gin's name, which is a shortening of the Dutch word for juniper, ''jenever''). A juniper-based spirit is made by fermenting juniper berries and water to create a "wine" that is then distilled. This is often sold as a juniper brandy in eastern Europe. Juniper berries are also used as the primary flavor in the liquor Jenever and sahti-styles of beers. Juniper berry sauce is often a popular flavoring choice for quail, pheasant, veal,
