A reliable old favorite around these parts is the snowball bush, viburnum opulus. Mine is from a rooted cutting my mom gave me. It's the kind of plant that gets passed on from generation to generation. Mine is planted in the back corner of the yard, and I think I like it best when it is at the edge of an open area that way. It is especially pretty in the evening light. I usually cut some of the blooms for a bouquet.
