Juniperus horizontalis douglasii
Description: Juniperus horizontalis 'Douglasii', commonly known as Creeping Juniper, is a low-growing, evergreen conifer known for its dense, spreading habit and attractive silvery-blue foliage. This hardy groundcover is ideal for erosion control, rock gardens, and as a low-maintenance landscape plant.
Foliage:
- Needles: The foliage is silvery-blue, scale-like, and soft to the touch. It maintains its color throughout the year, turning slightly purplish in winter, adding seasonal interest.
- Form: 'Douglasii' has a prostrate growth habit, spreading horizontally to form a dense mat. It typically reaches heights of 15-30 cm and can spread up to 1.5-2.5 meters.
Growing Conditions:
- Climate: Creeping Juniper is highly adaptable and thrives in a variety of climates. It is particularly well-suited to temperate regions of Australia. It can tolerate hot, dry conditions as well as cold temperatures, making it versatile for different areas.
- Soil: Prefers well-drained, sandy, or rocky soils. It can tolerate poor soils and is highly resistant to drought once established. Good drainage is essential to prevent root rot.
- Sunlight: Requires full sun to partial shade. For optimal growth and foliage color, it needs at least 6 hours of direct sunlight per day.
- Watering: Needs regular watering during the establishment period. Once established, it is very drought-tolerant. Water deeply but infrequently, allowing the soil to dry out between waterings.
Planting and Care:
- Planting: Plant in spring or autumn. Ensure the planting site has excellent drainage and ample space for the plant to spread. It can be used as groundcover, in rock gardens, or on slopes for erosion control.
- Pruning: Minimal pruning is required. Trim to shape and remove any dead or damaged branches as needed. Pruning is best done in late winter to early spring before new growth begins.
- Fertilizing: Apply a balanced, slow-release fertilizer in early spring to support healthy growth. Mulching around the base can help retain soil moisture and suppress weeds.
Pests and Diseases: Juniperus horizontalis 'Douglasii' is generally resistant to most pests and diseases but can occasionally be affected by:
- Juniper Scale: Small, white insects that can cause yellowing of the foliage. Treat with horticultural oil or insecticidal soap.
- Spider Mites: Can cause foliage to look speckled or bronzed, especially during hot, dry weather. Increase humidity and use miticides if necessary.
- Phomopsis Blight: Causes shoot tips to turn brown and die back. Prevent by avoiding overhead watering and ensuring good air circulation.
Landscape Uses: Creeping Juniper 'Douglasii' is an excellent choice for a variety of landscape uses, including:
- Groundcover: Its spreading habit and dense foliage make it ideal for groundcover in gardens and landscapes.
- Erosion Control: Well-suited for slopes and embankments where erosion control is needed.
- Rock Gardens: Its low, spreading habit makes it a great choice for rock gardens and around boulders.
- Coastal Gardens: Tolerant of salt spray, making it suitable for coastal landscapes.
- Containers: Can be used in large containers or planters for a cascading effect.
Notes:
- Tolerances: Highly tolerant of urban pollution, salt spray, and drought, making it suitable for various challenging environments.
- Maintenance: Low-maintenance once established, requiring little more than occasional watering and pruning.
Companion Plants: Pairs well with other drought-tolerant plants such as lavender, rosemary, and other junipers
