Italian cypress

Sun

Full sun; shelter from cold, drying winds near the colder end of its range.

Water

Water regularly while establishing; drought-tolerant once well rooted. Avoid persistently wet soil.

Soil

Well-drained sandy, loamy, chalky or stony soil; tolerates alkaline conditions and clay only where drainage is good.

Height

40-70 ft (12-21 m)

Spread

3-6 ft (0.9-1.8 m) for narrow garden forms; broad-crowned trees can reach 15-25 ft (4.6-7.6 m) or more.

Foliage

Evergreen. Dense, dark green, scale-like leaves on fine branching shoots; woody, rounded cones mature brown.

Growth

Moderate, often 1-2 ft (0.3-0.6 m) a year when young in suitable conditions.

Care needed

Medium

• Choose a named narrow form if you need a columnar tree; seedlings vary in shape and width.
• Water deeply during dry spells for the first two growing seasons, allowing the surface soil to dry between waterings.
• Spread 2-3 in (5-8 cm) of mulch over the root area, keeping it clear of the trunk.
• Do not feed routinely; use a modest spring feed only where poor growth suggests a nutrient shortage.
• Stake only if the root ball rocks in wind, using flexible ties and removing support once the tree is anchored.
• Allow for its mature height and keep it away from buildings in wildfire-prone areas; its resinous foliage can burn readily.

Pruning. In late spring or early summer, lightly trim wayward green shoots if needed to preserve the outline. Do not cut into bare old wood, which usually fails to regrow, and avoid topping the main leader.

Spring

Plant in colder districts once the soil is workable; water thoroughly and mulch.

Late spring

Lightly trim stray green shoots and check stakes and ties.

Summer

Deep-water young trees during dry spells and inspect browning foliage for mites or branch dieback.

Autumn

Plant in mild climates while the soil is warm, provided winter drainage is reliable.

Late autumn

Check drainage and keep mulch and fallen debris away from the trunk.

Winter

Gently brush off loose, heavy snow before it bends branches apart; do not strike frozen foliage.

• Plant matched narrow forms beside an entrance or at the end of a path to frame a view.
• Repeat columns along a formal walk, allowing room for their mature width.
• Use a single tree as a vertical accent among lavender, rosemary and low gravel-garden planting.
• Place dark evergreen columns behind pale stonework or silver foliage for year-round contrast.

Garden styles it suits: Italian / Tuscan, Modern Mediterranean, Formal, Architectural minimal, Dry gravel garden and Tuscan villa.

Plant it with: Lavender, Rosemary, Santolina, Rock rose, Bearded iris and Olive.

Wildlife: Dense foliage provides shelter and nesting sites for birds, and the cones supply seeds for some birds. Wind-pollinated rather than a useful nectar source; its pollen can cause significant seasonal allergies.

• Cypress canker causes scattered brown branches, sometimes with resinous lesions. Remove affected branches in dry weather, disinfect tools between cuts and avoid drought stress; severely affected trees may need removal.
• Spider mites cause fine stippling and bronzing, especially in hot, dry conditions. Check shoots over white paper, rinse accessible foliage and use a labelled mite treatment only if infestation persists.
• Root rot causes declining growth and browning in wet ground. Correct drainage and reduce watering; badly affected trees rarely recover.
• Snow, ice or strong winds can splay narrow crowns. Remove loose snow carefully and prune broken branches; avoid exposed sites where this damage recurs.

Not generally known to be poisonous to cats, dogs, horses or people. The foliage, cones and resin are not edible; chewing them may cause digestive irritation, and sap can irritate sensitive skin. Do not ingest concentrated cypress essential oil.

• Lawson cypress (Chamaecyparis lawsoniana)

  Usually has distinctly flattened foliage sprays, pale markings beneath and much smaller cones; Italian cypress has more three-dimensional shoots and larger, rounded woody cones.

• Mediterranean juniper (Juniperus excelsa)

  Can have a similar upright outline and scale-like foliage, but bears fleshy, berry-like cones rather than the hard, woody cones of Italian cypress.

• Pencil pine (Athrotaxis cupressoides)

  This Tasmanian conifer has short, thick, tightly overlapping leaves and smaller cones. In Australia, 'pencil pine' is also used for narrow Italian cypress, so check the botanical name.

Cupressus is the Latin name for cypress, and sempervirens means 'evergreen'; the common name reflects its long association with Italian landscapes.

Propagation. Grow from seed for variable trees, or take semi-ripe cuttings in late summer to preserve a narrow form. Cuttings can be slow and unreliable to root.

Accepted botanical name

Cupressus sempervirens

Native range

Cyprus, East Aegean Is., Iran, Kriti, Lebanon-Syria, Libya, Palestine and Turkey.

Measured

Soil pH 7 to 7.5. Average height 2500 cm.
