Granitic cliffs and bluffs directly fronting the open ocean, 10–30 m.
Small tree to 25 m tall in the wild, crown asymmetric, often open, flat-topped to widely conic in age; bark fibrous, thin, rich brown aging gray, broken into vertical strips; needles scale-like, bright to dark green, not glaucous; seed cone 20–32(38) mm diameter, spheric to elliptic, brown, shiny when fresh, more-or-less opening at maturity; seed 2.5–5 mm, not glaucous, dull red-brown to black; attachment scar more-or-less white, conspicuous (Bartel 2013). Distinguished from other native and exotic species of Hesperocyparis by large cone-size.
Identifiable year-round (male cones—February to March; female cones—March to May, ripening in August).
17-Mile Drive, Pt. Lobos State Natural Reserve (Monterey County).
Endemic to the Monterey Peninsula, Monterey County (CNPS 2010).
Perhaps the most common native tree in cultivation in coastal California, and therefore not in danger of immediate extinction, also cultivated in Europe and elsewhere. It has effectively naturalized along the Pacific Coast from Astoria, Oregon southward to Santa Barbara, California. Native stands are not stable from a lack of reproduction owing to tourist trampling.
