Dogwoods are great trees to have because they are interesting to look at year round! Summer brings beautiful flowers, and the bark is also quite nice. The leaves are full, too.
But I think the most interesting thing about dogwood trees are the shapes that they take. The branches are all twisty and grow every which way. They have an almost abstract quality to their forms. Many things of nature are pleasant to look at, but a flowering dogwood shrub is truly a thing of beauty.
