I'd be curious to know, as well. I saw a large number of them being sold for reasonable prices at Fleet Farm last year (5 gal). If they do that again this year I'll probably pick up one or two myself. I like the naturalistic clump form, and 6 or 8-foot spread woud look better than 15x4 IMO anyway. I've grown 'Regent' serviceberry (another alnifolia) in the past, and really love that species here on the northern great plains, as it's probably the hardiest serviceberry to high-pH soils (and native to the region). 'Regent' is a good berry producer, as it was developed in Canada for commercial fruit production. A hedge of Regent would be spectacular. Fall color was closer to yellow than orange for me, but they were all growing in partial/full shade. Still very nice color. The biggest problem is that rabbits absolutely love them in the winter (just like all Serviceberries), so they need protection. I used green-PVC-coated chicken wire year-round, but only winter protection might be necessary.

Ah, two-rose hobby, one of manual labor and another of intense emotional labor. Very pretty, good on you.

I've spent the past 6 years growing 15' trees to give my family privacy from the eyes of neighbors. The women in our house felt uncomfortable being in their bikinis in the back yard that was overlooked by a neighbor's second-story bathroom window used by a family with 3 teenage boys. That was one of the reasons we rarely used our swimming pool and eventually got rid of it. If the original poster is an attractive female and the neighbor is a dirty-minded, lonely, old man that doesn't know how to use the Internet to get his voyeuristic kicks...then there's a simple solution while you're waiting 6 years for those privacy trees to grow. You could always wear massive, baggy, oversized clothing, a large hat, and dark sunglasses while you garden. If there is nothing for him to see that interests him, he'll eventually stop peeping and will hopefully discover the Internet. You could also turn the tables and become the aggressor as some women successfully do. Peeping toms are usually the shy ones, and they can become completely crushed when confronted. The fact that he has joked about it with you perhaps reveals that he himself feels guilty about it. Recently-retired people very often struggle with mental and emotional issues. Even if you completely screen your property with vegetation and fences, you haven't really solved the underlying problem, at least not permanently. All he needs is a new vantage point. Or a tiny hole in the fence. Or a hidden camera. The problem is more of a human problem than a landscape design problem.

I like the simpler lines of the bed in Yardvaark's drawing and second the suggestion to make the bed include the crabapple. The plantings will create their own undulations - the bed edge doesn't need them unless to accommodate plants such as where it goes around the crabapple. If you don't want a staight line, one long sweeping curve looks far more graceful than many undulating curves and will also be easier to mow along. Consider the shape of the lawn you are creating, not only the shape of the garden bed. The deeper the bed, the more layers of plants you can fit in and the better the screening, and also the better the plants will look. I would consider at least a few evergreens for winter interest if nothing else. Either conifers or something like rhododendrons, many of which are hardy enough and will grow large enough. I would totally rethink several of your shrubs since what you have isn't suitable for a range of reasons. There are more shrubs than you have space for, even considering that you want them growing together as a screen. I'd replace the rose of Sharon, both because its shape and late leafing out makes it a poor screening choice, and because it only blooms for a few weeks at best, spending most of the season as a somewhat ungraceful green blob, so isn't even particularly ornamental to my eye. Two other shrubs, barberry and burning bush are both invasives. (I am frankly appalled that a nursery in this day and age would suggest either plant.) That means that birds eat the berries and then plant new ones wherever they leave droppings, most especially a problem in unmaintained areas such as woodland, fields and parks, but burning bush will give you many, many, many seedlings in your own yard as well. Barberry has thorns that make walking barefoot hazardous, and having grown up in a home with them, they catch every blown leaf and piece of trash which then need to be removed. Ugg! Here is an article that gives some alternatives, all of which I grow and like, or visit some other garden centers with your layout and see what else they have to suggest. Blueberries will also have stunning fall color along with white spring flowers and berries either for you or the birds. Far more attractive than burning bush with far less maintenance. One of my favorite long-blooming shrubs is Hydrangea paniculata which will grow fine in all day to half day sun, and blooms for something like 3-4 months here, depending on the cultivar. They range in height from something like 4' to 12', so you should be able to find one to suit. Limelight is quite popular, and my favorite, Quickfire, blooms from late June until hard freeze in October, starting white and then changing over to cherry pink. If the chain link is yours, it would be a great idea to grow some vines on it, since they would have a relatively shallow footprint, but add interest and screening ability. You could fasten trellises to the fence in places to allow them to grow taller. Or if it isn't yours, place trellises in front of the fence 6"-12". Site the trellises so that they block the views you want blocked from your most common viewing locations such as windows or seating areas since they will be there year round. A couple suggestions include a selection of the native honeysuckle Lonicera sempervirens 'Major Wheeler' with red flowers in a mass right now, and then continuing in lesser numbers all summer. There are also selections of the same species with flowers in yellow and orange, and there's a photo of Blanche Sandman in the article linked above. There are a number of clematis that would work such as jackmanii with deep purple flowers. Look for type 3 pruning (hard prune) since those are summer blooming and easiest to grow. I think you want to look at the ultimate size of your shrubs vs. the number specified. For instance, Lynwood Gold forsythia get to be 6'-9' in height and width, and really looks best in its natural fountain form. So plant it where there's space for it to grow with its natural grace, and only plant as many as there is space for (perhaps 3 instead of 4 in the space allotted?). Don't plan on pruning it please, though I do understand the need to prune the backside some to prevent it growing into the neighbor's yard - just try to plant far enough from the fence so that won't be needed. It can grow around the base of the crab a bit. I find that the Missouri Botanical Garden's Plant Finder is a great resource for accurate plant size if you type in just the name at the top as well as using the option to search for plants that fit your needs using the menu below. Once the screen of shrubs is planted, then I'd worry about adding the perennials. They are the icing on the cake and not involved with the main function of the bed, so they can be added later.
