Introduction
Gardeners who want an evergreen with personality will love the Haywire Port Orford Cedar. Unlike traditional upright evergreens with stiff formality, Haywire brings a playful twist: its thread-like blue-green foliage grows in slightly irregular sprays, creating a textured, modern look.

Origins & Description
The Port Orford cedar (Chamaecyparis lawsoniana) is native to the Pacific Northwest, where it grows into towering trees. Cultivated selections like ‘Haywire’ were bred for compact garden use and distinctive foliage character.
Haywire stands out for its thread-like sprays of blue-green foliage with a slightly twisted habit, giving it both elegance and whimsy. It grows at a moderate pace into a narrow, upright form about 8–12 feet tall, perfect for smaller gardens where a standard arborvitae or spruce might overwhelm.
Unlike some conifers that lose color in winter, Haywire retains a steady, muted blue-green tone year-round, making it a dependable anchor plant in all seasons.
Ideal Growing Conditions (Southeast Wisconsin Focus)
-
Light: Full sun to light shade. More sun enhances stronger color and tighter form.
-
Soil: Prefers moist, well-drained, slightly acidic soil. Avoid heavy clay that stays wet, as this can lead to root issues.
-
Moisture: Consistent moisture is important, especially in the first 2–3 years. Mulch helps retain soil moisture.
-
pH: Slightly acidic soils (5.5–6.5) are best.
-
Hardiness: Hardy to Zone 5. In exposed Wisconsin winters, wind protection (such as burlap screens) can prevent desiccation.
Planting & Establishment
When to Plant:
-
Spring (April–May): Ideal for strong establishment before summer heat.
-
Early Fall (September): Allows root growth while soil is still warm.
How to Plant:
-
Dig a hole twice as wide and equal depth as the root ball.
-
Place the plant so its crown sits level with soil.
-
Backfill with amended native soil, water deeply, and mulch with 2–3 inches of organic matter.
-
Keep mulch a few inches from the trunk to prevent rot.
Spacing: Plant 3–5 feet apart for screening; single specimens can stand alone with room to show off their character.
Care & Maintenance
-
Watering: Keep soil evenly moist, especially in hot summers. Deep weekly watering is better than frequent shallow watering.
-
Fertilizer: Feed lightly in spring with a conifer fertilizer or compost to encourage steady growth. Avoid excessive nitrogen.
-
Pruning: Minimal. Naturally tidy and narrow, but can be lightly shaped in early summer if desired. Avoid cutting into old wood, as regrowth may not occur.
-
Winter Care: In open or windy exposures, wrap young plants with burlap for the first few winters to prevent foliage burn.
-
Longevity: With proper siting and care, Haywire will provide decades of beauty and structure.
Landscape Uses & Companions
-
Vertical Accent: Perfect as a specimen tree in smaller gardens or mixed borders.
-
Privacy Screens: Narrow habit makes it useful where space is tight.
-
Modern Gardens: Its unusual texture pairs beautifully with clean architectural lines.
-
Companions: Works well with ornamental grasses, hydrangeas, viburnums, or perennials like coneflowers and sedum for year-round layering.
Seasonal Calendar (Wisconsin)
-
Spring: Plant new specimens, fertilize lightly.

Summer: Water consistently in dry spells. Enjoy steady, upright growth.
-
Fall: Good planting window through September; water before ground freezes.

Winter: Protect from harsh winds if in an exposed site.
Troubleshooting
