Description

Chamaecyparis Pis. Gold Mop is a compact, mounded selection of threadleaf false cypress prized for its cascading, “mop-like” sprays of fine, stringy golden foliage. The brilliant color holds through the seasons, brightest in full sun, and the soft texture adds year-round contrast to beds, borders, and foundation plantings. Its tidy habit, durability, and low maintenance make it a standout in mixed conifer gardens and modern landscapes alike.

With time, this evergreen forms a gracefully weeping dome. It performs best in well-drained, slightly acidic soils with consistent moisture and protection from harsh drying winds in colder climates. Minimal pruning is needed to maintain its natural, flowing silhouette.

Suggested Uses

Plant Details

Botanical Name

Chamaecyparis Pis. Gold Mop

Common Name

Chamaecyparis Pis. Gold Mop

Size & Growth

Mounded, cascading habit; typically 3–5 ft H × 4–6 ft W in ~10 years; may reach 6–8 ft with age in ideal conditions.

Hardiness Zones

USDA 4–8; protect from harsh winter winds in colder exposures.

Foliage Type

Evergreen, threadleaf (filamentous), golden-yellow sprays that stay colorful year-round.

Bloom Time

Primarily grown for foliage; produces inconspicuous pollen and seed cones in spring.

Growth Rate

Slow to moderate (about 4–8 inches per year in good conditions).

Light Requirements

Full sun for best gold color; provide afternoon shade in hot-summer regions to prevent scorch.

Attracts Pollinators

Low; primarily ornamental foliage—conifer cones are not significant for pollinators.

Indoor Friendly

Not suitable as a houseplant; best grown outdoors year-round within hardiness range.

Container Friendly

Yes, especially when young; use a large pot with excellent drainage and overwinter protection in cold climates.

Deer Resistant

Generally deer resistant; not a preferred browse, though hungry deer may sample new growth.

Pet Warning

Considered non-toxic to cats and dogs; ingestion of plant material may cause mild stomach upset—avoid allowing pets to chew foliage.

Fragrant

Foliage is mildly resinous when bruised; not noted for showy fragrance in the garden.

Cut Flower

Excellent cut evergreen for arrangements and winter containers; long-lasting texture and color.

Grows Well With

Other dwarf conifers, Japanese maple, Pieris, Azalea/Rhododendron, Blue Star Juniper (Juniperus squamata 'Blue Star'), Heuchera, and heathers (Calluna).

Care Tips

Planting Instructions

Plant spring or early fall. Dig a hole 2× the width of the root ball and the same depth. Gently tease circling roots, set the crown level with or slightly above surrounding soil, backfill with native soil amended with compost, and water thoroughly to settle.

Soil Moisture

Keep evenly moist during establishment; avoid both drought and soggy conditions. Once established, moderate drought tolerance, but best color with consistent moisture.

Soil Type

Well-drained, moderately fertile, slightly acidic soils (pH ~5.5–6.5). Incorporate organic matter to improve structure and drainage if needed.

Humidity

Average outdoor humidity is ideal; ensure good air circulation and avoid placement in low-lying, persistently damp spots.

Pruning Instructions

Minimal pruning required. Tip-prune lightly in late winter to early spring to shape. Avoid cutting back into old, leafless wood, which may not resprout.

Winter Care

Mulch 2–3 inches (keep mulch off stems). Water deeply before ground freezes. In exposed sites of Zones 4–5, shield from prevailing winds (burlap screen) to reduce winter burn.

Planting Depth

Set root flare at or up to 1–2 inches above grade to prevent water pooling at the crown. Do not bury the trunk.

Fertilization

Feed in early spring with a slow-release, balanced fertilizer for acid-loving evergreens (follow label rates). Avoid high-nitrogen or late-summer applications.

Special Care

Best gold color in full sun; provide afternoon shade in hot climates. Ensure sharp drainage (no standing water). Monitor for spider mites or bagworms; rinse foliage during dry spells and maintain airflow with proper spacing.
