Blue Pacific Juniper

The Blue Pacific Juniper, also known as shore juniper, is a prostrate hardy variety with a low trailing habit and short needle-like ocean blue-green aromatic foliage. This groundcover Juniper is commonly used for foundation plantings, around trees and shrubs, embankment plantings, beds, rock gardens, or planted along and allowed to hang over retaining walls. Plant this ground cover 2 ½ to 3 ft apart in a location that will receive full sun to light shade.

The Blue Pacific Juniper, native to Japan and belonging to the cypress family Cupressaceae, is highly valued for its ornamental beauty and low maintenance requirements. This plant is drought-tolerant and heat-resistant, thriving even in poor soil conditions. As a result, it is an excellent choice for various landscapes, from coastal areas to inland settings. Its resistance to common pests and diseases adds to its low-maintenance appeal.

Blue Pacific Juniper's spreading growth habit in landscaping makes it ideal for groundcover, erosion control, and filling large spaces. Its dense foliage acts as a natural weed barrier, reducing the need for frequent weeding. It also works well as a border plant, in rock gardens, or as a striking focal point in your landscape design.

When planting Blue Pacific Juniper, ensure it gets full sun to partial shade and plant it in well-drained soil. Regular watering is essential during the establishment period but becomes highly drought-tolerant once established. While pruning isn't usually necessary, you can trim it to maintain a desired shape or size.

Planting and Growing Blue Pacific Juniper

Blue Pacific Juniper thrives in full sun to partial shade and prefers well-drained soil that is slightly acidic to neutral. Once established, this evergreen shrub is drought-tolerant and suitable for areas with limited water availability. It can also withstand coastal conditions, including salt spray and sandy soils.

When planting Blue Pacific Juniper, start digging a hole slightly larger and deeper than the root ball. Gently loosen the roots before placing the shrub in the hole, ensuring it is at the same level as the surrounding soil. Backfill the hole with soil, firming it gently around the roots to eliminate air pockets.

Proper spacing is crucial for the healthy growth of Blue Pacific Juniper. When planting multiple shrubs, space them at least 3 to 5 feet apart to allow for adequate air circulation and prevent overcrowding. This will help maintain the natural form and shape of the shrub.

Frequently Asked Questions

How fast does Blue Pacific Juniper spread?

Blue Pacific Juniper is a fast-spreading groundcover that grows at a rate of 6 to 12 inches per year, eventually reaching a mature spread of 6 to 8 feet. Its low, dense growth habit makes it an excellent choice for erosion control, covering slopes, or filling large landscape spaces with lush, evergreen foliage.

What is the difference between Blue Pacific and Blue Rug juniper?

Blue Pacific and Blue Rug junipers are both low-growing evergreen groundcovers, but they differ in appearance and ideal uses. Blue Pacific Juniper has soft-textured, needle-like foliage with a lush green-blue hue, and it spreads moderately fast, making it great for erosion control on slopes.

Blue Rug Juniper features denser, scale-like silver-blue foliage and hugs the ground tightly, forming a flatter mat-like appearance, ideal for small spaces and low-maintenance landscaping. Both are hardy and drought-tolerant options for a variety of garden designs.

How far apart should I plant blue Pacific junipers?

When planting Blue Pacific junipers, space them about 4 to 6 feet apart. This allows room for their natural spreading habit while achieving full coverage over time. Adjust spacing based on how quickly you want the area to fill in.
