Canaan Fir
Abies balsamea var.
phanerolepis (Fern.)
Description:
Canaan (pronounced "Ka-naan", with emphasis on the last
syllable) is a relative newcomer to the Christmas tree market. It has many
similarities to both Fraser and balsam firs in growth and appearance.
Unfortunately, this similarity which has led to a great deal of confusion.
In 1909, a variety of balsam fir was described in the
literature as having cone scales extending from the bracts. This morphology was
a deviation from typical balsam fir cones where the scales are not extended.
This variety was then named "phanerolepis" which actually means conspicuous
scales. The scientific name of Abies balsamea var.
phanerolepis was assigned. The common names most often used were
"bracted balsam fir" and "Blue Ridge fir". Canaan fir had not, at that time,
been described separately.
Bracted balsam fir is found from Labrador to Ontario, and
from the coast of Maine to the higher mountains of Virginia and West Virginia.
The environments in which most natural stands are found is quite similar to
those of balsam fir and Fraser fir. The optimum habitat appears to be a cool
climate, abundant moisture and deep, well-drained soils. Soils are moderately
to strongly acidic.
In the mid 1930's, suggestions were made by several authors
that some specimens of the variety phanerolepis had a sufficient
number of traits of both balsam and Fraser fir that it should not be recognized
as a variety but as a separate species. These specimens were generally found in
West Virginia and Virginia. One author suggested the name be changed to
Abies intermedia to reflect this intermediate nature of the plants'
characteristics. The classification as a separate species has since fallen out
of favor, but some commercial nurseries still market the trees as Abies
intermedia.
Where does Canaan fir fit into the scheme? Canaan fir is
so-named because several of the original trees with the intermediate morphology
were identified from a limited area in West Virginia, generally referred to as
the Canaan Valley. Taxonomically, Canaan fir is considered the same as bracted
balsam fir and has the scientific name of Abies balsamea var.
phanerolepis. However, growth traits of the trees from these southern
regions are somewhat different than for other bracted balsam fir. Thus, there
occurs a dilemma as to how Canaan fir should be classified. There are lots of
opinions. The simplest solution is probably to consider Canaan fir as a special
ecotype of bracted balsam fir; this ecotype having unique characteristics as a
result of the environment to which it has been exposed. It is not currently
considered a separate species.
Range:
Because Canaan fir is probably best identified as an
ecotype, its range is somewhat undefined. Bracted balsam fir is found from sea
level in the Northeast to as high as 3,700 feet in Virginia. Original Canaan
fir collections for seedling production were made in a small area in West
Virginia at elevations generally above 3,000 feet, although trees of this
ecotype may exist in other areas.
Propagation:
Commercial propagation is by seeds. Information regarding
other techniques is limited but it is reasonable to assume methods appropriate
to the eastern fir species would be applicable.
Uses:
Because of the similarity of Canaan fir to the other eastern
firs, its uses are similar, although inaccessibility of stands limits the
amount of wood which can be harvested.
