Our spiraea is in bloom and it’s really pretty as a background plant. It’s flowers are small but borne in a profusion of white. There are little bits of green in the flowers, but that can really only be seen close up. Spiraea prunifolia, bridal wreath spiraea, is a native of China, Japan, Korea, and Taiwan and has been introduced in much of eastern North America. Interestingly, this double-flowered plant has the species name while the single-flowered variety, discovered later, is classified as a variety or form of the species. The name of the genus Spiraea comes from the Greek word speira meaning wreath.
