through the city, we are going to have two trees planted in the strip between the sidewalk and the street in front of our house. we have a list of trees to choose from, and I think I've narrowed it down the the purple leaf plum tree and the evergreen pear tree. I want something that blooms with flowers at some point in the year, but I'm also interested in something that keeps it's leaves all year so that it provides some privacy from the street. anyone have experience with either of these trees? I know the purple leaf plum is deciduous, but if it is overall a better tree, I'll choose that one.thanks for any input!
