The Rest of the Tagged Spruce–Norway, Black Hills, and Oriental

The needles of the Oriental Spruce almost look fake.

There are three other identified spruce trees in City Park. The Black Hills Spruce adds to the name confusion as it is also known as the White Spruce, Western White Spruce, Alberta Spruce, etc. To further cloud matters, there is a tree called a Black Spruce, which is distinct from the Black Hills Spruce. And on top of that, some sources identify the Black  Hills Spruce as Picea Glauca, the exact same taxonomic name as the White Spruce. On the City Park Self-Guided Tree Tour the tree is identified as Picea glauca var.densata. Apparently the Black Hills Spruce is more of a geographically distinct tree rather than a biologically distinct tree.

Black Hills-1
Black Hills Spruce

The Trees of North America website shows the range of this tree as being the northern part of the continent at a latitude that does not include Colorado but does include Wyoming. A Black Hills Spruce, the official tree of South Dakota, was the Capitol Christmas Tree in 1997. It is often used as a home Christmas tree.

One of the more unique spruces in the park is the Oriental Spruce (Picea orientalis), which is native to Asia Minor. This tree is said to grow to 50 to 60 feet and twice that height in its native environment. The specimen in City Park is more bush-sized. Although this is a slow growing tree, I suspect this little tree has not been in the park all that long.

The branches with their needles almost looks fake!

 

 

 

 

 

 

Norway-1
Norway Spruce

The Norway Spruce (Picea abies) is not native to the North American continent but is widespread in Europe. It has been “introduced” to the eastern part of North America. This tree is often grown in this country for Christmas trees, taking eight to eleven years to reach the ideal height of six to seven feet. One problem of using this in-house is that it tends to lose its needles rather quickly and must be freshly cut to be used for any length of time.

The lumber from this tree is probably of more importance in Europe than it is in this country, but due to many of its properties–spreading root system, hardy wood, a shape which keeps it from suffering much damage in ice and snow–it makes a good windbreak tree.

The branches can also be used for spruce beer, the lumber for sounding boards, pulp, and paper. The pitch can be made into varnish and has medicinal uses.

The Oriental Spruce E47

The Oriental Spru

 is in an entirely new area of the park. To find this tree, drive all the way down Oak Street into the ballpark parking area or enter from Mountain Avenue. As Mountain is separated by a median, you will need to be heading east to access the parking lot. The tree, looking more like a shrub, is in the strip between the parking lot and the New Mercer Canal, toward the more northern end of this land. It is the only  evergreen in the area. 

Both the Norway Spruce (B112) and the Black Hills Spruce (B111) are accessible from the diagonal parking on Oak Street between Jackson and  McKinley. Both trees are across from 1320 West Oak, the large red brick house with the sloping roof. In both instances the tags are easy to find.

 

 

 

 

December is for Christmas Trees and Our First is a Champion

A popular tree to decorate for Christmas

Every year trees are brought to the nation’s capitol to adorn the Capitol lawn, outside the Whitehouse, and sometimes in the interior of the Whitehouse. The National Christmas Tree has been displayed, cut or planted, in the President’s Park as well as other spots. This tradition started in 1923. The most common tree used is a variety of spruce.

Although the U.S. Capitol Christmas Tree tradition began before 1970, every year since then a different national forest has provided the tree. The White Spruce has been the tree of choice twelve times, the most of any single species. The tagged White Spruce (Picea glauca) in the City Park Arboretum near the intersection of City Park and Sheldon Drive is not only a native to Colorado, but a state champion tree. This tree probably does not call to mind a tree to decorate, though, as it is quite tall and somewhat spindly looking.

PB060067
The State Champion White Spruce

The USDA shows this species as having a very northern range, including Wyoming, but not Colorado. The Forest Service shows its range as even more restrictive. North American Trees (Preston and Braham, 2002) appears to agree with the USFS. The map on the Gymnosperm Database  also shows the distribution as very northern, mostly Canada, but goes on to list a number of states where the tree is native, again Wyoming but not Colorado. North American Trees says these trees do not reach maturity until 250-300 years and the Gymnosperm Database says the oldest tree, growing in the Yukon, is over 668 years old.

White spruce lumber has been used for sounding boards in violins and other instruments, for pulp, general construction, and Christmas trees. The National Christmas Tree Association suggests their short needles make them ideal for hanging ornaments.  I examined the branches of the tree I bought for my house this year, and I’m thinking it very well may be a white spruce.

The tree is significant for wild life and its roots were used by Native Americans to weave baskets and bind canoes. A British Columbian website includes making snowshoes and bows in its uses. Resin was turned into a gum to stick arrowheads to arrows. Like most of the other trees reported on thus far, this one, too, has medicinal properties, including antiseptic, respiratory, and wound care. It has also been investigated for its relation to diabetes!

PB290008
The needles and cone of the White Spruce

This specimen (A94) can be located by studying the tall conifers at the Northeast corner of City Park and Sheldon Drive. There are ten trees on this corner, but only two of them are conifers. The more northern of the two is the tagged tree, although I suspect the second tree is also a white spruce.
