Ashe juniper and cedar are two popular evergreen trees in Texas, but they have some key differences. Ashe juniper is native to the state and can thrive in a wide range of conditions.
In Texas, ashe juniper trees can grow up to 50 feet tall, while eastern red cedar trees typically reach heights of 30-50 feet. Ashe juniper also tends to have a more sprawling growth habit.
One of the biggest advantages of ashe juniper is its ability to tolerate drought, making it a great choice for water-conscious gardeners.

Ashe Juniper vs Cedar
Cedars and junipers are often confused with each other due to their similar appearance and aromatic wood, but they belong to different genera.
Cedars are limited to four species within the Cedrus genus and are native to the Himalayas and the Mediterranean region, whereas junipers are found in various parts of the world and belong to the genus Juniperus.
Here's a quick comparison of the two:
The Texas Mountain cedar, also known as Juniperus Ashei, is actually a type of juniper and not a true cedar, highlighting the importance of accurate identification.
Trees
Cedars and junipers are both evergreen coniferous trees, but they belong to different genera: Cedrus and Juniperus, respectively.
True cedars are limited to four species within the Cedrus genus and are native to the Himalayas and the Mediterranean region. This means you won't find them growing wild in many parts of the world.
Junipers, on the other hand, are typically shrubs with needle-like leaves and bluish cones that resemble berries. I've seen these cones on juniper bushes, and they're quite distinctive.
Here's a quick rundown of the key differences between cedars and junipers:
It's worth noting that juniper wood is used for producing juniper berries, a key ingredient in gin.
Know Your Natives
Ashe Juniper vs Cedar, it's a common debate among landowners and tree enthusiasts. Ashe Juniper is actually a native tree to central Texas, found in mountainous rocky areas and locations where natural fires didn't often spread.
One of the most surprising facts about Ashe Juniper is that it's one of the most efficient water users among native trees in central Texas. It's usually the last species to die in a drought, and it grows very successfully in places where few other species can.

Ashe Juniper is often mistakenly thought to be a water hog, but the truth is that it requires less water per diameter inch than a Live Oak. This is a crucial fact to consider when deciding which trees to remove or retain on your land.
The shade value of trees is often overlooked, but it's a critical factor in soil desiccation. The Sun causes exponentially more desiccation of the soil than any amount or type of plant. A tensiometer can help demonstrate this, showing how the soil moisture levels differ under an Ashe Juniper copse versus a neighboring field.
Ashe Juniper has another important benefit: it significantly minimizes erosion of topsoil. When a raindrop hits the soil, it slowly drips onto the ground, whereas other trees can cause erosion. The topsoil under an Ashe Juniper is often deeper and richer in nutrients.
Here are some key facts to consider when deciding whether to remove or retain Ashe Juniper on your land:
- Native tree to central Texas
- Efficient water user
- Usually the last species to die in a drought
- Requires less water per diameter inch than a Live Oak
- Significantly minimizes erosion of topsoil
- Rich in nutrients and beneficial bacteria
Texas Tree Species
Texas is home to a diverse range of tree species, but none are as prominent as the Ashe Juniper and Cedar trees. The Ashe Juniper, also known as post cedar or blueberry cedar, is primarily found in the east and south of the Edwards Plateau, covering over 8 million acres of rangelands.
The Ashe Juniper is known to thrive in rocky, limestone, gravel, and deep fertile soils. Both the Ashe and Redberry junipers can be found in several regions, including the Rolling Plains and Cross Timbers.
The Redberry juniper, on the other hand, is mainly west of the Edwards Plateau and east Trans-Pecos, covering more than 11 million acres in Texas. It's worth noting that the Redberry juniper overlaps with the Ashe in several areas.
Here's a quick comparison of the two main juniper species in Texas:
- Ashe Juniper: primarily found in the east and south of the Edwards Plateau, covering over 8 million acres
- Redberry Juniper: mainly west of the Edwards Plateau and east Trans-Pecos, covering over 11 million acres
These trees are indeed famous for their pollen, which is a notable characteristic of the juniper species in Texas.
Texas Mountain Facts
The Texas Mountain cedar is a tree that's commonly found in the Texas wild, but did you know it's not actually a true cedar? It's scientifically known as Juniperus Ashei, making it a juniper instead.
The pollen from Mountain cedar trees is a major culprit behind "cedar fever", especially during high pollen season. People with allergies often struggle with it, and it's no wonder why - the pollen grains are quite large and abundant.
Here are some key stats on where you can find Mountain cedar trees in the US:
The residents of central Texas are usually the worst hit by the release of cedar pollen, which can be a real challenge for those with allergies.
Texas Mountain Facts
The Texas Mountain cedar is a fascinating tree, and here are some interesting facts about it. They are not true cedars, but rather junipers, scientifically known as Juniperus Ashei.
The Mountain cedar is commonly found in central Texas, where it covers over 8.6 million acres of forests. You can also find it in Missouri and Arkansas, but Texas is where it really thrives.

People with allergies know that the pollen from the Mountain cedar is a major culprit. The grains are large and abundant, causing issues for many during the high pollen season, also known as "cedar fever".
The Ashe Juniper is a native plant from Northeast Mexico and South-central US to South Missouri. This means it's been growing in Texas for a long time, and it's not going anywhere anytime soon.
Texas: Differences
Texas is home to two main juniper species: Ashe and Redberry. The Ashe juniper covers over 8 million acres in the east and south of the Edwards Plateau.
These trees are primarily found in rocky, limestone, gravel, and deep fertile soils. You can also find them in south Texas and northwards to the Rolling Plains and Cross Timbers.
The Ashe juniper is a native plant from Northeast Mexico and South-central US to South Missouri. It's also known as Mountain Cedar or post cedar/blueberry cedar.

The Ashe juniper is often confused with cedar trees, but they have some key differences. For example, junipers tend to be shrubs, not trees, and they don't grow as tall as cedars.
Here are some key differences between junipers and cedars in Texas:
- Junipers have flat needles and produce tiny berries, while cedars have fan-shaped leaves and grow small cones.
- Juniper barks are brown or gray, while most cedar barks are brown or red.
- Junipers grow in hardiness zones 7-10, while cedars prefer zones 6-9.
The Redberry juniper, on the other hand, is mainly found west of the Edwards Plateau and east Trans-Pecos. It covers over 11 million acres in Texas and overlaps with the Ashe juniper in several regions.
Both species are famous for their pollen, which can be a nuisance for residents in central Texas. The Ashe juniper is particularly notorious for releasing its pollen, affecting the residents of central Texas the most.
Location and Habitat
The Ashe Juniper, also known as Mountain Cedar, is primarily found in central Texas, where it covers over 8.6 million acres of forests.
It's a native plant to the region, originating from Northeast Mexico and South-central US to South Missouri.
The United States Forest Service reports that it's also present in Missouri and Arkansas, but central Texas is where it's most concentrated.
Growth and Size
Ashe juniper trees grow at different rates, ranging from 0.58 to 1.94 meters per year, depending on the site conditions and other unique factors.
Some Ashe juniper trees show little change in the first 10-20 years, then experience rapid growth after 20 years.
The Ashe juniper's growth rate is typically slow to moderate, and it can reach a height of up to 33 feet, but in exceptional circumstances, it can grow taller, up to 49 feet.

What Is Growth Rate?
Growth rates can vary significantly among Ashe Juniper trees, with some growing as much as 1.94 meters a year.
The individual growth rate can depend on the condition of the site, with some trees showing rapid growth after 20 years.
In fact, some Ashe Juniper trees show little change in the first 10-20 years, only to experience rapid growth afterwards.
Trees that grow exponentially in their first years may see their rate decline later on, indicating that growth is not always linear.
The growth rate can be as low as 0.58 meters a year, highlighting the importance of considering individual factors when assessing growth.
Ashe Size: Maximum Height

The Ashe Juniper's maximum height is quite impressive. It typically grows to 33 feet, but some exceptional circumstances can allow it to reach 49 feet.
Its growth rate is slow to moderate, which can impact how tall it gets. This means it may take some time to reach its full potential.
This evergreen tree stays resilient throughout the seasons, and its robust root system helps prevent soil erosion.
