This is the idea.
As the outer corner focal points, we narrowed our Collins corners tree choice to Cornus kousa 'Milky Way.'
Milky Way dogwood has a height of about 20 feet, and a spread of about 15-20 feet, with a broad columnar shape, eventually widening at the crown to a more horizontal habit, and the specimens we selected branch low on their trunks. It features white flowers, red fruit, and dark green summer foliage which turns to a good wine color in the fall.
This cultivar was introduced by Wayside Gardens for the 2007 season. It was selected for its abundant, long-lasting, and showy blooms, followed by a heavy crop of large, attractive, strawberry-like fruits (loved by birds). It also features very ornamental bark. The vigorous tree flowers in June.
It is adaptable to full sun and most soils, and is resistant to many pests and diseases, including Anthracnose. While it requires moderately evenly moist soil, once it is established this spring in our clay soil, it should be tolerant of relatively dry summer conditions.
We've bought two trees from Chapon's today (plus 14 other shrubs--sadly we didn't get a discount. I hope they decide to do this in the future, either for garden clubs, and/or for Phipps members and/or for Botanic Garden members), which will be delivered next Friday, and installed by Blackridge's own Tom Fossick and his landscaping crew (412-377-2790 or 412-829-1812) shortly thereafter.
We can use some help schlepping water so that we give our new trees and shrubs a good start, so if you'd like to help, please let us know.
