They're red pines, and they're about 3 feet tall right now, maybe 4. (It's hard to get the combination of heights right when you plant on a slope and want to leave a nice berm to help hold in water.) I know they don't look like much, but about five years ago now, I planted some white pines, and now here they are:
So things do grow!
Happily, my neighbors' dog is here and helped me. (NOT.)
When I first moved here, about 11 years ago now, I planted 6 trees. Two white pines (not the ones above), two tamaracks (one has died, alas), a hawthorne, and this sugar maple. It's always a bit slow to leaf out in spring, but it sure has grown!
