Grow in average, medium moisture, well-drained soils in full sun to part shade. Best in full sun in the northern part of its growing range, but appreciates some afternoon part shade in the southern part of its range. Best performance is in moist, fertile soils in cool summer climates with above average humidity/rainfall.
Xanthocyparis nootkatensis is commonly called Nootka cypress, Alaska-cedar or yellow cypress. It is native to moist soils in bottomlands, along streams and in ravines along the Pacific Coast from southeastern Alaska to northern California. It is an evergreen conifer that will grow slowly to as much as 60-90' tall in the wild and live for 1000+ years. Drooping sprays of small, scale-like, bluish-green leaves. Rounded seed cones to 1/2” diameter. Bark is gray and peels in loose scales. Trunk is buttressed at the base. Although it may grow from 60-90’ tall in the wild, it usually grows much shorter in home landscapes. This species was reportedly found by A. Menzies in Nootka Sound in 1793.
This plant was originally described in the genus Cupressus, which many botanist consider to be correct, but has also been placed in Chamaecyparis and Xanthocyparis (as done here). Some strong evidence suggests, however, that it maybe should be placed in the monotypic genus Callitropsis.
Specific epithet means of Nootka Sound, British Columbia.
‘Pendula’ is a slender, pyramidal, strongly weeping form that may grow to as much as 35’ tall and 12’ wide over 35 years, but is often seen growing much smaller. It is an excellent specimen tree that features a nodding central leader with widely-spaced ascending to arching to horizontal branches from which droop branchlets clad with flattened sprays of scale-like blue-green to gray-green leaves. Leaves will emit an unpleasant odor when rubbed or crushed.
No known serious insect or disease problems. Plants generally have some susceptibility to juniper blight, root rot and certain insect pests such as bagworms and juniper scale. Watch for red spider mite. Plants may struggle in the St. Louis area where environmental conditions do not favor most conifers.
Near patio or deck. Effective near bodies of water.
