Hesperocyparis macrocarpa (Hartw.) Bartel
Cupressaceae (Cypress Family)
Synonym(s): Callitropsis macrocarpa, Cupressus macrocarpa, Neocupressus macrocarpa
USDA Symbol: HEMA22
An artistic, horizontally-branched tree growing 30-50 ft., sometimes taller. Conical in youth, the tree becomes broad and spreading with age. Medium-sized evergreen tree with large cones and with symmetrical crown when young or where protected; often becoming irregular and flat-topped when exposed to high winds. Soft-textured, dark-green needles are scale-like and flattened against the branchlets; the overall effect is like a braided bullwhip.
The gnarled, picturesque Monterey Cypresses growing on sea cliffs are a favorite photographic subject. The 2 native groves are protected within Point Lobos Reserve and Del Monte Forest at Point Cypress. It is widely planted as an ornamental, hedge, and windbreak along the California coastline and grown in forest plantations for timber in South Africa, New Zealand, and Australia.
