Glad you asked that question. I may be mistaken, and will be happy to be corrected, but it's always stuck in my mind that there not all evergreens are pine trees. For some reason, Hemlock sticks in my mind as an evergreen (none pine) to be careful with. Then again, I'm going on information that I remember being taught many years ago.....who knows, maybe the Hemlock thing is a false, old tale?
