Detailed Breakdown of Blue Star Juniper vs. Wichita Blue Juniper
Blue Star Juniper (Juniperus squamata ‘Blue Star’)
Scientific Perspective:
Juniperus squamata, commonly known as the Flaky Juniper or Hartford Juniper, is native to the Himalayas. The cultivar ‘Blue Star’ is a highly sought-after dwarf variety, celebrated for its incredibly dense, globular to irregular-mounding habit and its striking, silvery-blue, awl-shaped needles. These needles are typically 0.5 to 1 cm long and arranged in whorls, giving the plant a plush, almost cushion-like appearance. The “star” in its name refers to the star-like arrangement of its needle clusters. It is a dioecious evergreen shrub, meaning individual plants are either male or female, though for ornamental purposes, this distinction is usually not significant. Its slow growth rate is a key characteristic, typically reaching only 2-3 feet in height and a similar spread over many years.
Practical Applications:
The Blue Star Juniper is exceptionally versatile for smaller-scale gardening. Its compact size and slow growth make it an ideal choice for:
Borders and Edging: Planted along pathways or garden beds, it provides a consistent, low-profile blue accent.
Foundation Plantings: Its tidy habit prevents it from overwhelming the foundation of a house.
Container Gardening: It thrives in pots and containers, bringing its color and texture to patios and balconies.
Knot Gardens and Formal Designs: Its dense form can be used to create geometric shapes or low hedges.
Common Myths to Avoid:
Myth: Blue Star Junipers can be pruned into any shape.
Reality: While they can tolerate light shearing, aggressive pruning can remove the characteristic dense, mounding form and may result in unsightly gaps. It’s best to allow its natural shape to develop.
Myth: They need constant watering.
Reality: Once established, Blue Star Junipers are remarkably drought-tolerant. Overwatering is a far greater risk and can lead to root rot.
Wichita Blue Juniper (Juniperus scopulorum ‘Wichita Blue’)
Scientific Perspective:
Juniperus scopulorum, the Rocky Mountain Juniper, is a native species found in the western United States and Canada, often growing in harsh, arid environments. The cultivar ‘Wichita Blue’ is a popular selection known for its strong, upright, columnar habit, often described as a narrow pyramid or exclamation point. It possesses feathery, scale-like foliage that is a vivid, silvery-blue color, which is particularly intense in full sun. This juniper is also dioecious. Unlike the slow-growing Blue Star, Wichita Blue is a relatively fast-growing conifer, capable of reaching heights of 15-20 feet and a spread of 4-6 feet within 10-15 years, making it a significant landscape element.
Practical Applications:
The upright form and striking color of the Wichita Blue Juniper lend themselves to more prominent landscape roles:
Specimen Planting: Its dramatic form and color make it an excellent focal point in a garden or lawn.
Vertical Accents: It can be used to add height and structure to a planting scheme, breaking up horizontal lines.
Screening and Privacy: Planted in a row, its columnar growth can create an effective, albeit slow-growing, evergreen screen.
Formal Gardens: Its strong vertical lines complement formal garden designs.
Entryway Planting: Flanking a doorway or gate, it adds a touch of elegance and color.
Common Myths to Avoid:
Myth: Wichita Blue Junipers will always stay narrow.
Reality: While it is columnar, it will broaden over time. Ensure you provide adequate space for its mature width, especially if planting multiple specimens.
Myth: They are susceptible to juniper blight.
Reality: While junipers can be prone to certain fungal diseases like cedar-apple rust and various blights, ‘Wichita Blue’ is generally considered to have good resistance, especially when planted in well-draining soil and full sun, which promotes good air circulation. Proper spacing is key to preventing disease spread.
Comparing Growth Habits and Foliage
The most significant difference between Blue Star Juniper vs. Wichita Blue Juniper lies in their growth habit and foliage appearance. Blue Star Juniper is a low-growing, spreading shrub that forms a dense, rounded mound, rarely exceeding 3 feet in height but often spreading wider. Its needles are short, sharp, and have a distinct silvery-blue hue that is most pronounced in cooler weather. Wichita Blue Juniper, on the other hand, is a tall, slender, columnar tree that can reach heights of 15-20 feet or more, with a narrow spread of only 4-6 feet. Its foliage consists of soft, feathery, scale-like leaves that are a consistent, vibrant silvery-blue year-round.
Soil and Water Requirements
Both Blue Star and Wichita Blue Junipers are remarkably adaptable and are prized for their drought tolerance once established. They thrive in full sun (at least 6-8 hours of direct sunlight daily) for the best color and growth. They are also tolerant of a wide range of soil types, from sandy to loamy, but excellent drainage is paramount. They will not tolerate consistently wet feet, which can lead to root rot. When planting, amend the soil with compost to improve structure and fertility, but ensure the planting site allows water to drain away freely.
Watering: Water deeply and regularly until the plants are established (usually the first year). After establishment, watering should be infrequent but thorough, allowing the soil to dry out between waterings. Overwatering is a common cause of failure for these otherwise hardy plants.
Planting and Care
Planting:
1. Choose the Right Spot: Select a location that receives full sun and has well-draining soil.
2. Dig the Hole: Dig a hole that is twice as wide as the plant’s root ball and just as deep.
3. Prepare the Plant: Gently remove the juniper from its container. If the roots are circling, gently loosen them with your fingers or a small trowel.
4. Position the Plant: Place the juniper in the hole so that the top of the root ball is level with the surrounding soil.
5. Backfill and Water: Fill the hole with a mixture of the original soil and some compost. Water thoroughly to settle the soil and eliminate air pockets.
6. Mulch: Apply a 2-3 inch layer of organic mulch (like pine bark or wood chips) around the base of the plant, keeping it a few inches away from the trunk. This helps retain moisture, suppress weeds, and regulate soil temperature.
Care:
Pruning: Blue Star Junipers generally require minimal pruning, primarily to remove any dead or damaged branches. If shaping is desired, do so lightly in late spring or early summer after the new growth has emerged. Wichita Blue Junipers can be pruned to maintain their columnar shape or to remove any wayward branches, also best done in late spring or early summer. Avoid pruning into old wood where no foliage exists, as it may not regrow.
Fertilizing: Junipers are not heavy feeders. A light application of a balanced, slow-release fertilizer in early spring is usually sufficient. Over-fertilizing can lead to excessive, weak growth and reduced cold hardiness.
Pest and Disease Management: Both varieties are generally pest and disease resistant when planted in appropriate conditions. Monitor for spider mites, especially during hot, dry periods, and address any signs of fungal diseases (like blight) by improving air circulation and ensuring proper watering practices.
Common Mistakes to Avoid
Overwatering: This is the most common killer of junipers. Ensure excellent drainage and allow the soil to dry out between waterings.
Planting in Shade: While junipers can tolerate some partial shade, full sun is essential for their best color and compact, healthy growth. Shade can lead to leggy, sparse foliage and increased susceptibility to diseases.
Poor Drainage: Planting in low-lying areas or heavy clay soil without amending can lead to root rot.
Over-pruning Blue Star: Avoid shearing Blue Star Junipers into unnatural shapes; their beauty lies in their natural mounding habit.
Underestimating Mature Size: While Blue Star is slow-growing, Wichita Blue can become quite tall. Ensure you have adequate space for its mature height and spread.
Expert Tips or Pro Insights
Enhance Blue Color: For both varieties, planting in full sun and ensuring adequate air circulation will maximize the vibrancy of their blue foliage. Cool temperatures in fall and winter often intensify the blue hue.
Companion Planting: Blue Star Junipers pair beautifully with plants that offer contrasting textures and colors, such as ornamental grasses, sedums, and heathers. Wichita Blue Junipers make striking companions for deciduous shrubs with colorful fall foliage or broadleaf evergreens.
Seasonal Interest: Remember that junipers provide year-round structure and color. Consider how their blue tones will complement or contrast with other plants in your garden throughout the seasons.
Watering Strategy for Drought Tolerance: Once established, a deep watering every 2-4 weeks during prolonged dry spells is more beneficial than frequent, shallow watering. This encourages deeper root development.
