Well, there is screening windows, and there is screening bathroom windows. And whether you already plan to use curtain/shade but just want some additional fuzzing-out of you and your neighbor's views of each other (from either direction).Depends also on window location and angles and whether you may spend time at night (lighted interior/dark outside) naked in front of the window! I wouldn't rely on some plants for that kind of privacy that close to another house. That's when you might need glass block or other translucent material as noted above. Also whether the window otherwise has a good view, located so you can leave window uncovered much of the time, provides key light for an adjacent room, and so on, that would lead you to preserve clear glass at all costs. So it's a balance between being able to go in and out of your BR without fear, and preserving windows when you can.

I love Lady Banks rose too. I had one at my last Scottsdale garden in full bore sun and it was fine--it loved it. Let us know if you give it a try and how it works out. Like the others mentioned, it will need help sticking to/climbing a block wall (you can use those small adhesive dots which stick to the wall and then tie the major canes to those, or you can put up thick wire (with space between the wire and the wall); anything that will help the roses climb. If you're still looking for options, good old hopseed (Dodonea) is an option. It will become a very tall dense hedge and is very low water once established (give it a good drink twice a week its first summer or even longer if you want it to continue growing quickly). With extra water it grows fast, and then if you ease it back to little water over a long period of time the growth will slow down and be more compact/durable. Just a thought. Keep us posted! Take care, Grant By the way, I'm sure most everyone knows that the largest single rose plant in the world is here in Arizona: the so-called Tombstone rose in Tombstone AZ (you have to pay a small fee to see it and they do sell rooted cuttings of it, though you can buy the same type of plant almost anywhere here). It's a white flowered Lady Banks rose. Talk about a house eater! I love them. Here is a link that might be useful: Tombstone Rose

Pierce, just be aware that you will need a male holly for every 5-7 female plants to get berries. Because you will be planting tightly, you might be able to stretch it to one per 10 females. Most of the male forms I know of are shorter growing than the females, in general. You could get around this by using 1-gallon males and planting in the same hole as the females/'Nellie R.Stevens' as you space them out - they can grow up and be available, but are 'hidden' among the mass of the females. I know 15 gal. 'Nellie R. Stevens' are available, but can't speak as to price. While the 'Nellie R. Stevens' are a good hedge plant, if you wanted to mix in another type of tree, the Thuja 'Emerald Green' (a.k.a. 'Emerald Beauty' or 'Smaragd') is another good hedging plant, growing fairly fast to 12-15', and about 3-5' wide. You can fairly easily find 5 gallon plants, at about 4-6' tall - and pay more for them than 1 gal. - so they might be good where you want immediate height. While running bamboos will provide a solid screen once they are established, they will also RUN!! I have pulled out runners that are up to 8' long, and about 6" deep, in the spring. As long as you mow faithfully, you can keep them in check. However, even asphalt won't stop them from coming up - cement MIGHT! You can buy barriers, but you need to make a 3' deep trench for the barrier to be effective, and even then, you will probably have to watch for escapees over the top. Clumping bamboos are much better behaved, and will expand, but stay where you plant them.
