This chance seedling was discovered in Anniston, Alabama, by Hayes Jackson. Multiple flat, star-like, sterile white flowers come into flower in June and continue up to the first frost. Hayes Starburst smooth hydrangea (Hydrangea arborescens 'Hayes Starburst') blooms on new wood, so it will reliably flower in the Chicago area, regardless of how much damage is done to the stems of the plants over winter.
