Shrubs Ashe Juniper

Introduction to Ashe Juniper

Ashe Juniper, also known as Mountain Cedar or Post Cedar, is a native evergreen tree/shrub widely appreciated in San Antonio landscapes for its dense blue-green foliage and adaptability. It typically grows between 15 and 30 feet tall, with a spread of 10 to 20 feet, making it an ideal medium-sized plant.

Its foliage is dense and offers a fine texture with a distinctive blue-green color that remains vibrant year-round. While it produces small blue-green flowers, they are not prominent as ornamental features. Its main appeal lies in the year-round dense cover it provides.

In landscaping, Ashe Juniper is commonly used for privacy screens, windbreaks, erosion control, and as a wildlife habitat due to its thick foliage, which offers shelter for birds and other animals. It thrives best in full sun but can tolerate part-shade conditions.

Ashe Juniper requires minimal maintenance once established, making it a low-effort choice for homeowners.

Maintenance

• Soil: Prefers dry, rocky soils but adapts well to various soil types common in San Antonio.
• Watering: Highly drought tolerant; watering is mainly needed during the establishment phase.
• Light: Thrives in full sun but tolerates partial shade.
• Pruning: Occasional pruning may be necessary to maintain shape or manage size, but it generally grows well without frequent trimming.
