Alaskan Cedar
Callitropsis nootkatensis
treeAlaskan cedar is a large coniferous evergreen tree native to the Pacific Northwest, characterized by gracefully drooping branches and flattened, feathery foliage with a pleasant aromatic scent. It typically grows 40-60 feet tall in the wild, with a narrow, columnar form that becomes more pendulous with age. The tree produces small woody cones and reddish-brown, shredding bark that adds winter interest.

Establishment
2-5 yearsTree develops deeper root system and begins characteristic graceful branching; foliage becomes denser; growth accelerates
Continue regular deep watering; maintain mulch layer; prune only to remove dead/damaged branches; ensure good air circulation
Active Growth
5-20 yearsVigorous upward and lateral growth; characteristic pendulous branching becomes pronounced; tree reaches 20-40 feet
Maintain moisture especially during heat; thin crowded branches if needed for form; monitor for spider mites in dry conditions
Mature Form
20+ yearsTree reaches full ornamental form with graceful, weeping branching structure; cones produce viable seed
Minimal pruning needed; remove lower dead branches; monitor for disease in humid climates; maintain moisture during droughts

Fun Facts
- 🌱 Alaskan cedar is not a true cedar (genus Cedrus) but rather a false cedar; it is more closely related to cypress and juniper, which is why its scientific name includes 'Callitropsis'.
- 🌱 The wood is so rot-resistant that standing dead trees (called 'snags') can remain erect for decades and are prized habitat for woodpeckers and other cavity-nesting birds.
- 🌱 In its native range along the Pacific coast of North America, Alaskan cedar can live for over 3,000 years, making it one of the longest-lived trees in North America.
