I had a similar problem. I removed the fence around my pool when I had the deck redone. I wanted a privacy screen close in so I used a combination of things. I made 5 trellises from 4X8 vinyl lattice and put them on landscape timbers about 2 feet above the ground and kind of framed them. Basically this made an 8 ft wide trellis with the top about 6 ft high. On two of these, i put Lady Banskia roses..they are evergreen. One one I am growing Confederate Jasmie and one one Carolina Jasmine (which isn't as thick a screeen as the confederate). The 5th trellis has another climbing rose but isn't really a good screen. I sort of placed these trellises at intervals around the deck toward the corners but not exactly symetrically.. In between these are a variey of other plants, viburnum which makes a bigger lush tree and lorepeltum for it's rich red coloration. The bed around my deck is of varying width from maybe five feet at the back of the pool to 10 feet on one end. So I also have room for compacta and some other hollies as well as day lillies, a few sago palms etc.. I used this other stuff for a low to the ground screen but also to give some texture /color differences. I've been shaping these other plants, some round, some square etc.. I'm definitely not a gardening artist, I just like to play and add stuff, but the effect is nice.

Evergreen or deciduous? For evergreens, you're limited a little by our climate. You didn't mention how much sun it will get but I'm assuming a new subdivision and full sun. Also, you need to keep in mind that the more narrow the plant, the more plants it will take to complete the hedge. I just did a landscape plan for a large estate. The 120' hedge of Columnar Hick's Yew (it's in shade) on 2 foot centers at $100 per plant, well, you can see how expensive that gets fast. Some less costly shrubs that should work for you would be Juniper or Aborvitae. There are a lot of different varieties that would work but I'd look for 'Witchita Blue' Juniper or 'DeGroot's Spire' Aborvitae. If you are buying them all at once, you might be able to have a nursery order them in for you and negotiate a wholesale price since you'll be buying so many. Retail price on a 2', 2 gallon size DeGroot's Spire at Glover Nursery is $24. You could also do a 'Graham Blandy' Boxwood. For deciduous shrubs, you have more options, some of which include 'Fine Line' Buckthorn, 'Helmond Pillar' Barberry. I would really encourage you to do a mix of shrubs. It will be more interesting over time and more forgiving if something happens to some of the shrubs. If you do all evergreens in a straight line, you risk 'missing tooth' syndrome WHEN (not if) a plant dies. Vary your line so it's not perfectly straight and a mix of a couple different shrubs and it will all look good.

Not able to delete this but I posted on another Sub-forum - http://forums.gardenweb.com/discussions/3775568/m=23/need-advice-tall-outdoor-privacy-plants-for-shaded-area in the hopes of getting some ideas

To get something tall enough and dense enough to block that view and thin enough to fit in there may be tough. Especially if you need to block it from various angles. Hard to tell how much space you actually have to work with. This forum is a bit slow, you may want to ask on the Shrub Forum to get more responses. tj
