If sometimes plant breeders are guilty of hyperbole in their plant name selections, this is not the case with Incrediball—the commercial name for the 'Abetwo' cultivar of H. arborescens. In spite of the huge, densely packed 12-inch flowers the shrub produces in abundance, the sturdy stems on this plant will not allow the flowers on this white hydrangea to flop in the mud. One potted plant will make a gorgeous anchor in your summer border, or you can plant several for a showy hedge.
