I'd love a native dogwood but can it really stand up to full sun ??

Crepe myrtle would be a wonderful choice too. I have several varieties.

The maple may get too big and the root system could be a problem with the pond. I'm not familiar with all the different maple just know some will get very big.

Some smaller trees that prefer full sun, but can handle part shade: Check out a Fringe Tree (Chionanthus virginicus), which puts our very fragrant and profuse white flowers in late May. It grows 12 - 20' high. It's a slow grower, so try to buy as large as you can (5'). There is nothing like it in the spring when it flowers.

Or a Sweet Bay Magnolia, which also flowers white in June. It is semi-evergreen, but this far north will probably loose 2/3rds of its leaves. It grows 10 - 35' in height. I'm not sure of its rate of growth.

Kath has the right ideas, qualify the tree before installation.

Height, color (fall), root problems, seeds in the spring, leaves for compost?

Wolfe, don't block the view to the garage, where you have many colors, shapes, and sizes to look at.
