Engelmann's Spruce, Engelmann Spruce
Pinaceae (Pine Family)
USDA Symbol: PIEN
Large tree with dark or blue-green foliage and a dense, narrow, conical crown of short branches spreading in close rows. Engelmann’s spruce is a narrow, spire-like evergreen, growing 75-100 ft. tall. Its branches descend to sweep the ground and conceal the trunk. The coniferous needles are dark blue-green.
Its resonant qualities make the wood of Engelmann Spruce valuable for piano sounding boards and violins. This species was named after George Engelmann (1809-84), the German-born physician and botanist of St. Louis and authority on conifers.
The species of this plant is named for George Engelmann (1809-1884) who was born in Germany and settled in St. Louis, Missouri, as a young man.
