Planting history: presently unknown.

Description:

large evergreen tree, conifer
said to be intergeneric hybrid between Monterey cypress and Nootka cypress (Cupressus macrocarpa x Chamaecyparis nootkatensis, although the taxonomy of the latter is in dispute); said to be the only intergeneric hybrid among gymnosperms
leaves small, scale-like; in flat sprays
sterile; propagated by cuttings
fast-growing; very commonly planted as a screening hedge, but has resulted in property disputes because of tall, dense, overshadowing growth. Maximum height ca 130’; but shallow-rooted, so large trees tend to fall over
prefers full sun
