Geek Notes
According to Maurice Horn on the Joy Creek Nursery website, "Even though the Japanese name for this selection translates to 'white flower,' the flowers on this compact shrub are both pink and white. Spiraea japonica 'Shirobana' is also called, perhaps more aptly, 'shiburi' in Japanese referring to the dappling of colors in the flower heads." (www.joycreek.com)
