This summer, I visited the Boston area. I was struck by how beautiful the forests are there. They are shorter and more tangled-looking than our Western forests, but they have their own distinct beauty.
Pinus strobus, the Eastern White Pine, was the dominant conifer in the area. I did happen to find a broom very close to the Boston metro area, but I doubt that I will ever make it back there to collection scions. Plus, it was in a suburban area where I doubt that I could use a gun to retrieve them.
Nonetheless, it was fun to find this broom in an unfamiliar place. It just goes to show that mutations are ubiquitous :)
