Italian Cypress
Cupressus sempervirens
Italian Cypress is grown for its foliage rather than flowers, giving the garden structure and color all season long.
Mature size, hardiness zones, sun and the trait tags were checked against named botanical sources for this plant. The bloom months and water need on this page were not.
Growing Italian Cypress
Plant it in full sun. It prefers low water. It is hardy in USDA zones 7–10. Expect it to reach about 39 ft tall and 3.3 ft wide at maturity, in roughly 15 years.
When to plant Italian Cypress
Plant Italian Cypress in spring once the soil is workable, or by very early fall at the latest: an evergreen needs its roots down well before the ground freezes. For the middle of its hardy zones 7 to 10 range, that is February to April, or September on the fall side.
Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 8 in February.

Good to know about Italian Cypress
Curated from university extensions, botanic gardens and other primary sources, with the source named on every note.
Worth knowing
Its three worst problems, canker, bark beetles and spider mites, all pounce on a stressed tree. Keep it unstressed and you fend off all three at once. per University of Maryland and University of Arizona
When to prune
It holds its narrow column unaided, so skip routine shearing; every cut is a canker entry point. Only prune to cut out canker-flagged branches, disinfecting tools between cuts. per NC State and University of Maryland
Dry, but never stressed
Established trees want low water and hate wet roots. But do not let one bake into severe drought or heat, which invites canker. Water deeply but rarely in real drought. per NC State and University of Arizona
Cypress canker has no cure
Highly susceptible to Seiridium canker: branches fade green to yellow to reddish-brown from sunken, resin-oozing cankers. No fungicide cures it, so cut out flagged branches and reduce stress. per West Virginia University and University of Arizona
Spider mites, the top pest
Spider mites are its most common pest. They bronze and stipple foliage, peak in spring and fall, and flare on hot, dry, dusty, stressed trees. Horticultural oil helps. per UC IPM and UGA
Wet soil brings root rot
Its one non-negotiable is sharp drainage. In wet, poorly drained soil, Phytophthora and other root rots set in, mainly on young or stressed trees, and there is no cure. per Penn State and NC State
Not a listed pet poison
Generally treated as non-toxic: it is absent from the ASPCA pet-poison list and carries no toxicity flag, though the foliage is not edible. per ASPCA
What pairs well with Italian Cypress
Good companions share its growing conditions and add something it lacks: an earlier or later bloom, a lower carpet in front, or structure through winter.
