Chamaecyparis nootkatensis Aldrich Mountain

Alaskan Yellow Cedar

A rare form of cedar

A rare and fascinating conifer with fern-like, green, aromatic leaves growing to 3metres (10ft). It is extremely hardy and cold resistant and an interesting plant for the collector. It is now thought to be a form of Thuja plicata, or a natural hybrid with it, rather than a form of Alaskan Yellow Cedar. In the garden if is a light feathery contrast to large-leaved evergreens and good to add height to lower planting.


Plant in full sun or semi shade in a bed or border, in gravel or in a pot or container.


Any well-drained, but moist fertile soil. Dislikes extreme drought. In a pot use a lime-free, loam based compost. No pruning required.

A relic of the last Ice Age found at 5300ft on Aldrich mountain, Central Oregon

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
