Karoonda Cypress
HES-per-oh-SIP-air-iss mak-ro-KAR-pa
Cupressus macrocarpa
Callitropsis macrocarpa
Native to (or naturalized in) Oregon: 
  • Conifer, evergreen tree, narrow columnar form; grows less than 2 ft per year; may reach 14 ft tall and 1 ft wide (4 × 0.3 m) in 10 years. It is similar in appearance to a well-known selection of the Italian or Mediterranian Cypress and is sometimes labeled as an Cupressus sempervirens ‘Karoonda’.  It may be a good substitute for the Italian Cypress since it is reportedly more cold hardy.
  • Sun
  • Hardy to USDA Zone 7?
  • Taxonomy: Monterey Cypress has been classified as Cupressus macrocarpaCallitropsis macrocarpa, and more recently as Hesperocyparis macrocarpa.  As of 2024 Hesperocyparis (western cypress), (hesperus, -a, -um; Latin, of the west, western) is listed as the correct classification by Plants of the World Online, World Flora Online, and the Gymnosperm Database. There is disagreement about this classification, with some scientists continuing to use Cupressus in preference to Hesperocyparis.
