So we are going to do some type of evergreen across the back and side of our yard... maybe leyland cyrprus/arborvitae or something like that. In the corner we want to plan a flowering tree. We would like one that blooms for more than like 3 days. color doesnt really matter.

I have fallen in love with dynamite crepe myrtles but am having trouble finding it as a single stem tree.

any recommendations would be greatly appreciated!
