Depending on taxonomic viewpoint there are between 50 67 species of juniper widely distributed throughout the northern hemisphere from the Arctic south to tropical Africa in the Old World and to the mountains of Central America in the New World. There are many species to choose from in the landscape most of which are tough and very drought tolerant. Some species are widely used as ground covers others for hedging but primarily they are used as evergreen anchoring plants in mixed borders and foundation plantings. =Description= Junipers vary in size and shape from tall trees 20–40 m tall to columnar or low spreading shrubs with long trailing branches. They are evergreen with either needle like and/or scale like leaves. They can be either monoecious or dioecious. The female seed cones are very distinctive with fleshy fruit like coalescing scales which fuse together to form a berry like structure 4–27 mm long with 1 12 unwinged hard shelled seeds. In some species these berries are red brown or orange but in most they are blue they are often aromatic (for their use as a spice see juniper berry). The seed maturation time varies between species from 6–18 months after pollination. The male cones yellow and catkin like with 6 20 scales most shed their pollen in early spring but some species pollinate in the autumn. Many junipers (e.g. J. chinensis J. virginiana ) have two types of leaves seedlings and some twigs of older trees have needle like leaves 5–25 mm long and the leaves on mature plants are (mostly) tiny (2–4 mm long) ...
