colorblind, You have 40 feet you want to cover and $500 to spend. You have been given the best advice of experts on would be a better choice than the three you insist you want to use. Your choice seems to be based on what local nurseries want to quote you or your dictates for an instant dense screen. You are imposing a choice that fits your insistence on instant screening which excludes the advice of possible better choices. I think you could easily find someone to plant 5 Green Giants or other suitable trees to fill your 40 foot space. If the people you have had quote the project cannot meet your needs it would be far better to keep looking. Pool seasom is over for the year; it will not start up again until Memorial Day which gives you all fall and even Spring to find someone who can plant 5 good sized trees to screen your neighbor's pool. It won't be peek proof right away. You have obviously lived with your own pool with no screen for a while. What's the hurry? Why not do it right? You seem to want a short-term, instant fix to something you will have to look at for a long time. If you don't want suggestions, then put the three alternatives you have had dictated to / by you in a hat and pick one out and live with it. What's the hurry? You have a fence, your neighbor will have a fence and you will have a growing screen of good sized trees. I don't see the reason to rush and put in something that you may regret in a few years. Jon

I found this link might help.. http://www.hintsandthings.co.uk/garden/climbers.htm I would like to get something for Charlotte NC zone 7 that flowers if possible that can grow fast and its evergreen.. any help is appreciate it..

It's often more efficient to go and see what is available to you at local outlets first and then make your choices from among those you like the look of. Unless you are planning to order the plants in from elsewhere. Otherwise this looks better written than usual. Only a small number of evergreen kinds but all the shrubs included are supposed to be reliable. So it could still help you zero in on something that will work out: Oklahoma Proven: Plant Selections for Oklahoma | Oklahoma State University (okstate.edu)

mad_gallica--Re hardiness of Cephalotaxus. Some sites say it is hardy to zone 5 and I had one at my old property when I was certainly still zone 5. I know it came through one spell of minus 16 degrees. My name says zone 6A, but with climate change, I expect I'm now likely zone 7--winter temps haven't gotten below maybe 10-12 degrees in years with a once or twice dip to maybe 3-4 degrees. It actually rarely even gets into the teens even at night. I miss winter! I've never seen it around here either, but you don't see much other than what can be purchased at Lowes around here. My new neighbors were astonished that plants could be purchased through mail order.
