Juniper Tree Root System

Juniper tree

Junipers can act as a comfortable home for wildlife. Juniper trees are evergreen in nature that can make winters look beautiful. Coniferous trees and shrubs in the genus Juniperus of the cypress family Cupressaceae are known as junipers. Juniperus communis is the most common variety of Junipers. Juniper trees are found throughout the Northern Hemisphere. They have an excellent adaptation to dry soil. Junipers normally grow well in a variety of welldrained soil types, but the majority need full sun or moderate shade to flourish. One of the highest tree lines on earth is created by the juniper forest, which can be found at 4,900 meters in the northern Himalayas and southeast Tibet. There are about 50 to 60 species of Junipers available. Without their roots or branches, evergreen bushes like junipers cannot thrive. Juniper trees can live for between 350 to 700 years.

Physical Description

Needle-like juniper leaves

Junipers can grow anywhere between 20 and  40 meters in height and have a variety of shapes including columnar or low-growing shrubs with long, trailing branches. They have the scale or needle-like leaves and are evergreen. Depending on their species, they can be monoecious or dioecious. Junipers do not belong to the genus Cedrus. Although they may resemble needles in young plants, the leaves of these evergreen conifers typically adopt the shape of flattened scales in mature plants. Junipers are found in various regions of Europe, Asia, and North America. It can be found in India’s Himalayas at an elevation of 1500–4000 meters above mean sea level. They grow well in warm, sunny locations, particularly on mountain slopes.

Root System

Junipers can tolerate dry conditions, which frequently cause other trees and plants to die. A huge underground root system that can make up two-thirds of a tree’s total bulk is its well-kept secret. The taproot of juniper can reach a depth of 25 feet in a straight line in search of water. The roots of junipers are particularly tough; they frequently continue to develop even after being pushed over by the wind. Junipers are well adapted to dry soil. In addition to a mat of fibrous roots closer to the soil’s surface to collect rainwater, they typically contain a very deep taproot to absorb water from deep soil layers. Most junipers are drought-resistant to some extent, making them a viable choice for arid regions. Junipers thrive in areas that are sunny and have good soil drainage.


Alligator Juniper


The unique bark of the Alligator juniper, which resembles the scaly, spotted skin of an alligator, gave rise to its common name. Depending on the environment, this species can grow either into a shrub or a tree. Other popular names for junipers are oak-barked, thick-barked, western, and mountain cedar. This plant thrives in rocky, arid environments.

California juniper


In the Southwest of North America, the California juniper is often found as a sizable shrub, however, it can occasionally develop into a medium-sized tree in the wild. It has reddish-brown cones and blue-gray leaves that resemble scales. It is frequently used to offer erosion control on dry slopes and is particularly tolerant of alkaline soils. It is frequently utilized in bonsai.

Chinese juniper


The Hollywood juniper is a variant of the Chinese juniper known as ‘Toruloso’. It develops a fascinating twisted appearance as it ages, making it a good specimen plant. Chinese juniper plants have needle-like leaves when they are young, but as they grow older, they have scale-like leaves. This juniper is among those that tolerate urban environments well, however it dislikes moist soil.

Common juniper


This juniper shrub can be found all over the world. It thrives in both alkaline and acidic soils and adapts to a variety of environments, including windy places. Depending on its surroundings, this plant can assume a variety of shapes. Some cultivars grow slowly and make good ground coverings, but the specific form may resemble small, erect trees. This unusual juniper lacks scales and has needle-like leaves instead.

Creeping Juniper


Creeping juniper performs admirably as a ground cover and lives up to its name. It is quite flexible and can work in a variety of environments and soil types. When the plants develop, the leaves change from needle-like to scale-like. Blue-white berries with a waxy coating make up the cones. This plant is available in more than 100 cultivars, some of which have yellow foliage. Locally, this shrub may also go by the name creeping Savin juniper or trailing juniper.

Drooping Juniper


The name “drooping juniper” refers to the way the branchlets droop. These upright trees feature needle-like leaves as juveniles, which change into flat scales as they develop. The cones of this tree are greenish berries that turn purplish-brown as they develop, and its bark is reddish-brown or grey and sheds in strips.

Red Cedar juniper

 Red Cedar

One variety of juniper that has a very strong scent and is occasionally used to ward off insects is red cedar. This upright tree has scale-like dark blue-green foliage. The grey to reddish-brown bark frequently flakes off in vertical strips, and the bottom of the trunk is occasionally fluted. It is employed in big screen plantings or as a specimen tree. This tree, unlike many junipers, can tolerate some precipitation, however, it does not like to wallow in soggy soil.

Greek juniper


The stinking juniper, a species with a similar look but lighter green leaves, is frequently found growing beside the Greek juniper, a big shrub or tree. Even the edges of stony cliffs can support the growth of these resilient trees. Like many junipers, young Greek junipers have needle-like leaves that develop into flattened scales as the tree ages. The gray-green foliage is covered in huge, up to 6-foot-diameter trunks. Purple-blue berries grow inside the cones of female plants.

One-seed juniper


Large shrubs or trees with numerous stems and a dense, rounded crown are known as one-seed junipers. On mature plants, the cones resemble dark-blue berries with a waxy white coating, and the leaves are flattened scales. The bark is gray-brown and peels off in slender vertical strips, revealing scarlet wood beneath. The single seed that usually exists in the cone or berry gives the plant its name. Other popular names of this plant are cherrystone juniper and single-seed juniper. Although this tree is now extremely uncommon over much of its original range in Mexico, it is very prevalent in New Mexico and the Southwestern United States. Although the wood from this plant is frequently utilized for fence posts and other reasons, it is rarely planted as a landscaping specimen.

Rocky Mountain juniper

Rocky Mountain 

The mountain red cedar, Rocky Mountain cedar, or Colorado red cedar are other names for this close relative of the eastern red cedar. A small to medium-sized tree, the Rocky Mountain juniper typically takes on a pyramidal appearance as it matures. In mature trees, the leaves resemble scales, and many junipers have cones that resemble the blue-green berries with a waxy-white coating that they are most commonly found in. Skyrocket is a particularly bluish-green, slender cultivar. One of the juniper species that are especially vulnerable to cedar-apple rust is this one.

Utah Juniper


These shrubby trees thrive in Utah’s alkaline soils and are a common sight, earning the names Cedar Breaks National Monument and Cedar City, Utah. This juniper can also be seen growing in Arizona and other western U.S. regions, where it is also referred to as a big berry juniper or desert juniper. Unlike other junipers, this tree has foliage that is a paler shade of yellow-green. The fruit or cone is bluish-brown and has scale-like mature leaves. The gray-brown bark may peel off in small pieces and the stems and branches are extremely substantial.

Western juniper


Throughout the year, the western juniper often referred to as the Sierra juniper, supplies food for a range of animals and birds like cedar waxwings who eat the berries. During the pioneer era, wood was employed for a wide range of purposes. This plant typically develops into a huge shrub or a small tree, depending mostly on the environment it thrives. Although it is frequently found in the wild, it is seldom planted as a landscape item.

Leaf System

The leaves of a young juniper are needle-like. Mature leaves are awl-shaped, spreading in whorls of two or three. Some species feature tiny, scale-like leaves that are pushed firmly to the rounded or four-angled branchlets. These leaves frequently have an oil gland. Many junipers, notably J. Chinensis and J. virginiana, have two different leaf types: immature plants have leaves that resemble needles and are 5 to 25 mm long, while mature plants have leaves that, most frequently, resemble microscopic scales and are 2-4 mm long.  Junipers are typically distinguished by their leaves, which can either take the form of needles or scales. Normally, all leaves start as needles that develop into scales as they mature. As a result, junipers have scales and needles at the same time. These can occasionally be found in separate branches or mixed in the same branch.

Fruit System

The component of the juniper that is referred to as the berry—or fruit—is the cone. Junipers are either monoecious or dioecious. The female cones have fleshy merging scales that held together to create small, berry-like fruits in shades of reddish-brown, orange, or blue. The majority of northwest species mature to a blue tint, while the other species appear red. These 1- to 12-unwinged, hard-shelled fruits range in length from 4 to 27 mm. The subglobose, bluish-black, dark purple fruit, which resembles a fleshy berry, measures 10 to 13 mm in diameter and is waxy on the outside. The fruit’s three scales, which are generally three and are elongated, oval, and lodged in the pulp, can occasionally gape and reveal bony seeds.
