Something old, something new? This bridal wreath could be the something old in that wedding custom. I can remember spiraea planted around my grandfather's parsonage. I can't remember seeing it around any new houses. It's a decoration that has fallen out of fashion. The bridal wreath name could apply to several introduced species and cultivars of spiraea. You may not see this in modern neighborhoods, but you might catch a glimpse where it persists wild in AL, AR, CA, CT, DE, GA, IL, KY, LA, MA, MD, MI, MO, MS, NC, NJ, NY, OH, PA, TN, VA, WV, NS, or ON.
