Cedars vs. Junipers: Telling Two Ancient Trees Apart
Learn how to spot and distinguish between cedars and junipers, exploring their origins, features, uses, and ecological roles.
Cedars vs. Junipers: Understanding Two Ancient Conifers
While cedars and junipers are iconic evergreen trees found across many landscapes, their similarities often cause confusion. In gardens, parks, and wild forests, these coniferous giants play crucial roles—yet they diverge in origin, biology, appearance, and uses. This guide explores their differences in detail, from scientific classification and visual features to growing needs, cultural history, and ecological importance.
Classification: True Cedars vs. Junipers
One of the first distinctions between cedars and junipers is their scientific classification.
- Cedars belong to the Pinaceae family (the pine family), under the Cedrus genus.
- Junipers fall into the Cupressaceae family (the cypress family), in the Juniperus genus.
This means that, despite the common name ‘cedar’ being applied to some North American species like the Eastern redcedar, true cedars do not grow natively in North America. Instead, many so-called “cedars” in North America are in fact junipers (Juniperus virginiana) or related trees.
Common Species and Distribution
- True Cedars: Native to mountainous regions of the Himalayas and the Mediterranean. Iconic species include the Lebanon cedar (Cedrus libani), Atlas cedar (Cedrus atlantica), Deodar cedar (Cedrus deodara), and Cyprus cedar (Cedrus brevifolia).
- Junipers: Found throughout North America, Europe, Asia, and Africa. Notable species include Juniperus virginiana (Eastern redcedar), Juniperus communis (Common juniper), and Juniperus scopulorum (Rocky Mountain juniper).
Origins and Natural Habitats
| Tree | Native Regions | Typical Habitat |
|---|---|---|
| Cedars | Himalayas, Mediterranean (Lebanon, Cyprus, Morocco, Turkey) | Mountainous areas, well-drained soils, cooler climates |
| Junipers | Tibet, Africa, Asia, Europe, North America | Open woodlands, rocky or sandy soils, arid to temperate climates |
Visual Differences: How to Tell Them Apart
Both of these trees can be evergreen and appear similar from a distance, but several notable differences make them distinguishable up close.
Needles and Foliage
- Cedars: Feature soft, flexible needles arranged in whorled clusters or fan shapes. Needles measure about 1–2 inches and feel softer to the touch. The foliage forms a feathered, brushy look on limbs.
- Junipers: Most have small, sharp, scale-like leaves, often pressed tightly against the twig. Young growth may have needle-like leaves but these become scale-like as the plant matures. Foliage forms a tighter, often spikier cluster than that of cedars.
Bark
- Cedars: Bark is usually reddish-brown to grayish-brown, scaly, and peels away easily in long strips or plates as the tree ages. The wood underneath can emit a distinct, pleasant aroma.
- Junipers: Bark is gray or light brown, flakier and often in strips as well, but tends to become more ragged and stringy with age.
Cones and Fruit
- Cedars: Produce upright, barrel-shaped woody cones that sit on top of the branches. Each cone starts green and maturing to brown, breaking apart to release seeds.
- Junipers: Instead of hard cones, most species produce berry-like, blue or bluish-purple seed cones, familiarly called “juniper berries.” These are actually fleshy cones, not fruit, and are standard ingredients in gin and game dishes.

Size and Form
- Cedars: Typically taller and broader—often reaching heights of 50–100 feet, sometimes up to 130 feet in their native ranges. The trees have a majestic, spreading form.
- Junipers: Vary from broad, low-growing shrubs (as little as 10 feet) to upright trees about 40–60 feet, though some species grow taller. Many garden junipers remain shrub-sized, favored for hedges or groundcover.
Hardiness and Growing Conditions
| Tree | USDA Hardiness Zones | Soil Preference | Light Requirement |
|---|---|---|---|
| Cedars | Typically 6–9 | Moist but well-drained, slightly acidic | Partial shade to full sun |
| Junipers | Usually 7–10 (some hardy to Zone 3) | Well-drained, tolerates poor/dry soils | Full sun preferred, some tolerate shade |
Cedars prefer steady, moderate moisture but struggle in soggy ground. They tolerate partial shade and benefit from mulching. In contrast, junipers excel in hot, dry sites and require excellent drainage. Drought-hardy junipers often thrive where cedars would falter.
Wood and Practical Uses
Cedar Uses
- Wood: Highly prized for its distinct fragrance, tight grain, resistance to rot, and insect-repelling properties. Common in construction (siding, shakes), fencing, furniture, chests, and closet linings.
- Essential Oils: Extracted from wood, leaves, and twigs for use in aromatherapy and natural insect repellents.
Juniper Uses
- Wood: Dense, often knotty and twisted, making it popular for rustic furniture, fence posts, and specialty woodworking. Also known for rot resistance.
- Berries: Used as the key flavoring agent in gin and as a spice in traditional dishes and game meats.
- Landscaping: Numerous groundcover, shrub, and small tree varieties for erosion control and drought-resistant lawns.
Ecological Roles
- Cedars: Act as key shelter for birds and small mammals in their native habitats. Their shade and leaf litter foster unique woodland microclimates. Some species host rare and specialized wildlife.
- Junipers: Important food sources—many birds and small mammals eat the “berries.” Dense branches provide nest cover. Junipers also stabilize thin, rocky soils and promote biodiversity in harsh environments.
Common Confusions and Misnomers
The term “cedar” is sometimes applied to trees that are not true cedars. For example, the North American eastern redcedar (Juniperus virginiana) is actually a juniper, not a cedar. Similar confusion surrounds western red cedar (Thuja plicata), which is not a true cedar either but belongs to an entirely different genus. Understanding Latin names and classifications helps avoid these mix-ups, especially when buying lumber or landscaping plants.
Quick Comparison Table: Cedars vs. Junipers

Choosing Between Cedars and Junipers in Landscapes
When selecting trees or shrubs for your property, both cedars and junipers offer unique benefits:
- Use cedars for tall screens, windbreaks, and where fragrant, premium wood is desired. Best for cooler climates and soils with reliable moisture.
- Use junipers on dry, poor, or sloped sites where drought tolerance and low maintenance are priorities. Ideal for hedges, erosion control, or aromatic berries.
Practical Identification Tips
- Look for fan-shaped or clustered soft needles and upright, barrel cones for true cedars.
- Seek out sharp, scale- or needle-like foliage and visible blue or purple “berries” for junipers.
- Bark texture: Peeling, aromatic, reddish-brown for cedars, versus flaky, more stringy grayish for junipers.
- Taller stature and broad, majestic shape often means cedar; more modest height or shrubby form suggests juniper.
Frequently Asked Questions (FAQs)
What is the main difference between cedars and junipers?
True cedars are members of the pine family (Pinaceae, genus Cedrus) and originate from the Old World (Himalayas and Mediterranean), whereas junipers are in the cypress family (Cupressaceae, genus Juniperus) and have a wider global distribution. Their needles, cones/berries, bark, and uses also differ.
Are eastern redcedar and western red cedar true cedars?
No. Both are misnamed. The eastern redcedar is actually a juniper (Juniperus virginiana), and western red cedar (Thuja plicata) belongs to a different genus entirely. Only trees in the Cedrus genus are true cedars.
Can you eat the cones or berries from these trees?
Juniper “berries” are edible in small amounts and traditionally used for flavoring (notably in gin and game dishes), but should not be consumed in excess. Cedar cones are not eaten and can be toxic.
Which is more drought-tolerant: cedar or juniper?
Junipers are significantly more drought-tolerant and adaptable to poor, rocky soils. Cedars, while hardy, require more consistent moisture.
How can I ensure my cedar or juniper thrives in my landscape?
Provide full sun for junipers, with well-drained soil. For cedars, ensure steady moisture and protection from winter dehydration or sun pockets. Mulching and proper site choice are critical for both.
