Cupressus sempervirens
  • Distinctive narrow columnar form — the classic Mediterranean garden silhouette
  • Soft scale-like dark-green foliage with year-round structure
  • Stays only 3–6 ft wide despite reaching 30+ ft tall — ideal for tight vertical accents
  • Best in protected, sunny, well-drained sites in the south Puget Sound

Italian Cypress is the iconic narrow columnar evergreen of Mediterranean garden design — the tight pencil-like silhouette has been used as a formal vertical accent for centuries. The dark green scale-like foliage holds year-round, and mature trees can exceed 30 feet while staying only a few feet wide. In the south Puget Sound, performance is best in protected, well-drained sunny sites; cold-sensitive cultivars can fail in extended hard freezes.

Planting and Care

  1. Planting. Plant in full sun with sharp drainage. Italian Cypress resents wet feet — avoid low spots and clay-bottom planting holes that hold winter moisture. Choose a site protected from cold drying winter winds. Dig a planting hole wide rather than deep, set the trunk flare at grade or slightly above in heavy soils, backfill with native soil amended for drainage, and mulch lightly.
  2. Watering. Deep weekly watering through the first two growing seasons. Established Italian Cypress is highly drought-tolerant. Avoid overhead irrigation that wets the foliage — it can promote canker disease pressure.
  3. Fertilizing. Light feeders. A single light application of balanced slow-release fertilizer in early spring during establishment years is sufficient. Mature trees in average soil rarely need fertilization.
  4. Pruning. Minimal pruning required — the natural columnar form is the primary ornamental feature. Light shaping in late spring through mid-summer is acceptable. Avoid cutting into bare interior wood.

Italian Cypress performs best in mild, sheltered south Puget Sound microclimates — Tacoma, Federal Way, and Des Moines waterfront sites are ideal. Inland Auburn and Sumner sites can experience winter dieback in hard freeze years; container culture or sheltered placement is recommended.
