  • Layered, fan-like dark green foliage with a soft Asian-garden character
  • Slow growth and tidy form — popular for rock gardens and Japanese-style plantings
  • Reddish-brown peeling bark adds winter interest
  • Many dwarf cultivars available for small spaces and containers

Hinoki Cypress is a slow-growing evergreen prized for its layered, fan-shaped foliage and refined character. The species and its dwarf cultivars are mainstays of Japanese-influenced landscape design across the south Puget Sound. Mature trees develop attractive reddish-brown bark that peels in long strips, adding winter interest. The dense layered foliage casts a calming dappled shade and resists most insect pressure.

Planting and Care

  1. Planting. Plant in well-drained, slightly acidic soil with full sun to light afternoon shade. Hinoki Cypress dislikes wet feet — avoid low spots and clay-bottom planting holes that hold water. Dig wide rather than deep, set the trunk flare at grade, backfill with native soil amended only if drainage is poor, and mulch.
  2. Watering. Deep weekly watering through the first two growing seasons. Once established, Hinoki tolerates moderate summer drought but performs best with supplemental water during the south Puget Sound’s late-summer dry stretch.
  3. Fertilizing. Light feeders — most established Hinoki Cypress need no fertilization at all. If foliage color is pale, a single light application of an evergreen-specific slow-release fertilizer in early spring is appropriate.
  4. Pruning. Minimal pruning required. Light shaping in late spring through mid-summer maintains form. Avoid cutting into old wood — Hinoki does not regenerate from bare branches the way arborvitae and other conifers can.

Hinoki Cypress thrives in south Puget Sound conditions — the cool maritime climate matches its native Japanese habitat closely. Plant in well-drained sites in Auburn, Kent, Tacoma, and Federal Way landscapes; avoid clay-bottom holes that hold winter moisture.
