I'm going to redo my front yard a want a small amount of privacy. My front yard slopes down about 2 feet to public sidewalk. I'm going to build a 1 ft tall wall and I would like to plant hedges along it on top. I'm going to need 42 ft long. I would like them to be between 4 and 8 ft tall and would like to be able to plant them without spaces.
Now about my area: I live in WI. There is NO shade as a tornado just took out all of my trees. My yard faces south. 6-8 mo of cold (sometimes extreme) and 4-6 of warm (sometimes extreme). I don't really want "evergreens" unless it's my only option, but I do want something that will be full all year round. Flowers are fine, but not necessary. I hope someone can help me figure out what to get.
