The Alaska Cedar is native to the North American continent. This tree exemplifies the classification confusion that strikes amateur tree lovers. On the City Park tour guide (revised 2015) the Alaska Cedar, also called the yellow cedar, nootka Cypress, Stinking Cypress, and Yellow-cypress, the nomenclature is given as Chamaecyparis nootkatensis. National Audubon Society Field Guide to North American Trees, Western Region (1994), and the 2002 edition of North American Trees (Preston and Graham) agree with this designation, but the Gymnosperm Database lists the same tree as Cupressus nootkatensis while The Sibley Guide to Trees (Sibley, 2009) calls it Callitropsis nootkatensis. The USDA site classifies it as Family Cupressaceae (Cypress Family), genus Callitropsis (Nootka Cypress), species Callitropsis nootkatensis. The U.S. Forest Service lists THIRTY-SIX different names for this same tree! For the moment, I will just call it the Alaska Cedar and let the botanists argue. The University of British Columbia discusses this same dilemma and solves the problem by using the nomenclature C. nootkatensis.
Although some sites list this tree as growing for 300 years, conifers.org states the oldest tree has a ring count of 1834 and lists the tallest as a specimen in British Columbia of over 200 feet. The lumber of the tree has been used for exterior purposes such as shingles, decking, and posts. A few sources mention the crushed leaves of this tree do not smell good. When used as firewood, the wood has a high BTU output. Wikipedia mentions that a tree may last 100 years as firewood! Seems like it would have to be a very large specimen, though. Some of the unusual uses it has been put to is as stadium seating and toys.
The Alaska Cedar may be another victim of climate change as a large number of these trees in Canada have died off in the last 100 years. This blog explains that the suspected cause of the die off is that these cedars have shallow roots that are susceptible to freezing, which can kill the tree. As the climate warms, the snowpack is not as deep or melts off early, leaving the roots exposed to cold night time temperatures.
The Weeping Alaska Cedar is a cultivar usually used for landscaping purposes. For its scientific name, add Pendula to your preferred name for the Alaska Cedar. It is thought that it can be grown in most of the United States.
The Alaska Cedar on the current Self-Guided Tour in City Park, Fort Collins, is E63. To find Chamaecyparis nootkatensis, head to Club Taco near the pool at the intersection of City Park and S. Bryan drive. This tree can be found across the street where the ditch and the fence around the miniature railroad tracks nearly form an angle. It is not known when this tree was planted.
The Weeping Alaska Cedar (Chamaecyparis nootkatensis Pendula) is located along Jackson Ave, across from 222 Jackson, near one of the exercise stations. This cultivar was planted in 1997.
