The Buttonbush ( Cephalanthus occidentalis) is an unusual shrub with curious white pincushion flowers. It is found in the wild all over the United States, usually in swamps and moist areas.  Growing up in rural Alabama, I remember seeing it in the woods behind our house.  It doesn't garner much attention until the blooms make their appearance.  Sources vary on the size of the plant. In the wild, it can get to 20 feet but in gardens, most likely under 12 ft. In my garden, it is about 4 feet tall after five years in the ground. It is located along the back fence in an area that doesn't get much supplemental water although I am working on the area and watering more often this year. The flowers have a slight honey-like fragrance. Bees love this plant! Text and photos by Phillip Oliver, Dirt Therapy
