Picea rubens (red spruce) is one of only 8 US native spruce species, and the only one whose natural ranges includes North Carolina. The entire range of red spruce starts in Nova Scotia and continues south to high elevations in the NC mountains. Genetic testing indicates that our red spruce evolved due to climate change during the Pleistocene (12,000 years to 2.5 million years ago), when it split off from Picea mariana (black spruce). Black spruce is now the only other nearby spruce, which currently resides from New Jersey north with a small population in Northern Kentucky.
Surprisingly, red spruce is virtually absent from piedmont gardens, probably due to the common wisdom that it doesn’t tolerated heat and humidity. As long as it’s given adequate amounts of Calcium (we aim for a pH of 6.5), it grows beautifully. Here is our 26 year old specimen, that didn’t get the memo that it’s shouldn’t grow here. Hardiness is Zone 3a-8a.
Red spruce wood is used to make high quality wood instruments like violins and acoustic guitars, but to avoid cutting down your lovely specimen, we recommend you stick with products that can be made from the foliage, like the infamous Red Spruce Beer.
