I am looking for a fast growing plant that I can use for a screen. I need about 10-15' minimum coverage, something that stays green in the winter time, doesn't require a lot of pruning (It can grow wild) and has the fasted growth rate. I though about a leyland cypress but I read somewhere that they can grow to 50' tall without pruning. Another plant I am trying to learn about might work well and that is a oakleaf holly. How fast do oakleaf holly's grow and does it look like that will fill my needs? Thanks a lot for any advice.
