An impressive ornamental tree in its own right, but best known in north-west Europe as a parent of Leyland Cypress (p. xxx).

A very limited natural range: just two areas on California’s Pacific coast, where it grows alongside Monterey Pine. It survived the last glaciation but could not later migrate to more suitable sites. Hot, dry conditions limit its growth, though where introduced it can thrive.

Monoecious. Serotinous.

Height 25m in natural range, elsewhere 45m or more. Bark fibrous. Leaves scale-like, in rounded sprays (not flattened). Female cones globose, 2–4cm, maturing after two years.

Not very cold-hardy (-12°C), so best planted in mild regions. Fast-growing and wind-firm. Resistant to salt-laden winds.

No notable associations where introduced.

Considered genetically vulnerable due to its tiny range.

Has timber potential but often heavily branched.
