There's a nice big Norway spruce on the corner of our lot. Here's a shot of a female cone. Norway is the most popular spruce in cultivation. Every year a few seedlings spring up around the yard. Thanks, squirrels! But for all their hard work, the squirrels have little to show. The seedlings never persist. Nevertheless, Norway does occasionally spread and persist. It's not too unusual to see small groves, mostly with old trees and younger ones venturing out. Because of their diffidence, it's a little hard to know when we should regard them as wild. FNA says they're in MN, and then rather vaguely that they are probably elsewhere. USDA reports them from CT, IL, KY, MA, MD, ME, MI, MN, NC, NH, NJ, NY, OH, PA, RI, VA, VT, WI, WV, NB, NF, NS, ON, and QC. And I would say they are probably elsewhere, here and around the world. Cultivated, Lenawee Co MI, 5/7/15. Pine family, Pinaceae.
