It seems to me one of the most confusing aspects of spruce trees is their many alternate names. One of the names for the Engelmann Spruce is white spruce, as well as silver spruce and the generic-sounding mountain spruce. At a glance, the various species look very similar, too. The Engelmann Spruce (Picea engelmannii) is a native of North America. Listed in Flora of Colorado (Jennifer Ackerfield, 2015) it is native to Colorado as well as Larimer County! Unlike the White Spruce written about last week, internet sources concur this one is a native and show its range being the western part of the continent, south to the New Mexico/Texas border and north to the British Columbia/Yukon border. Possibly the confusion with the white spruce is due to the two trees hybridizing? The Gymnosperm Database mentions that the oldest Engelmann spruce is in Colorado and has attained at least 911 years of age.
The fine needles on the twigs and branches of the Engelmann spruce are much more evenly spaced than those of the white spruce, reminding me of a bottle brush. From a distance, this is hard to distinguish. When examined closely, the spruce cones also have subtle differences; the ends of the Engelmann spruce cones appear to be toothed. Comparing the tagged park specimens, the cones of the Engelmann are also somewhat larger than those of the White Spruce. The Engelmann spruce is the second most common tree used for the Capitol Christmas tree with nine appearances since 1970.
The New York Times Style Magazine of December 3, 2017 short article “Chasing Pine” discussed a number of edible uses of conifers, including the historical spruce beer. Modern chefs make pine ice cream, pine aioli, and custard. Others use a spruce oil in drinks, Some sprinkle a spruce-sugar concoction on cookies.
The Englemann Spruce listed on the tree guide (D193) is at the Southwest corner of City Park and Sheldon Drive. You can access this corner by turning onto Sheldon Drive from Mulberry and parking near the intersection with City Park Drive. That corner of the park is lined by deciduous trees on the eastern and northern edges. Numerous conifers form the south edge along the lakeshore. The marked tree sits in front of the larger spruces, between an Oakleaf Mountain Ash and a Baker Blue Spruce. It has a perfect conical Christmas tree shape.
