Serviceberry should work. David

The problem with Amelanchier is that it too has berries/fruits - I don't know if it holds them or drops them. There are non-fruiting crabapples, which can be trimmed and trained to a better shape. Some of them also have reddish/purple foliage. Another possibility is redbud, including the cultivar Forest Pansy, with red/purple foliage, although the height may be too much.

Some of the flowering cherries might do, if you pick a small cultivar. Any of a number of weeping trees could also do - weeping redbud; weeping mulberry; weeping, grafted varieties of willow; weeping cherry - especially if you got a grafted one which wouldn't grow much taller. If you are ASSIDUOUS with the pruning, a standard, tree-form wisteria could be dramatic.

If it is sheltered, a small-growing deciduous magnolia could be very nice. If Vitex will grow in your area, it could also do - with dead heading, you should get bluish flowers several times in the summer, and an attractive winter shape. You can limb vitex up into a nice small tree. Several of the viburnums can also be limbed up into trees. Red Buckeye is another possibility.

There are selected cultivars of evergreens; Japanese false cypress, thuja, or juniper, etc., which will stay small. Some of them have gold, blue or variegated foliage, some of which will change color in the winter, the least interesting to a dull bronzey-brown.

Selected Japanes maples might also be very attractive, chosing for size and color. Since they range from weeping ones that can get to be 25' H x 20'W, to dwarfs that will never go over 5'. to 25' tall treees, there is one for almost any size. Almost all have good fall color, many are variegated or have interestingly shaped leaves, or both.

The birds will eat the serviceberry fruit before it falls.

What type of density do you want the plant to have. Seviceberry and Sweetbay magnolias will be more open. Most conifers and smaller magnolias such as the Little Girls series will be more dense.

If you like the idea of a japanses maple then there are a lot of different options and selections. A few nice selections are Koto-No-Ito, Shishigashira and Bloodgood. You may also want to consider a paperbark maple which has the added attraction of nice bark for winter interest.

Red Buckeye can be nice but the ones I have need some afternoon shade and the leaves often look bad by the end of summer.

If you want something different check out Ironwood(Carpinus Carolina), Pawpaw or American Smoketree(Cotinus Obovatus) David

paper bark maple is hardy and attractive.....fringe tree is tough and flowers nicely
