OK, I think I have narrowed my plant choice for the "leftmost" (as you view the photo) corner of my front yard close to the house. My options are as follows:

- multi-trunked Pagoda Dogwood

- multi-trunked Eastern Redbud

- multi-trunked Apple Serviceberry (Amelanchier x grandiflora)

All three of these trees have been touted on several webpages discussing ornamental trees for SE Wisconsin. I prefer the multi-trunked look, but I am flexible. To refresh your memory, here is a snappy of our yard:

Once I get this corner highlight tree in there, I think the rest of the "foundation" planting will fall into place. As always, thanks for your thoughtful comments!
