Syn. Wim Rutten
A new and distinct cultivar of Hydrangea plant named `Wim Rutten`, characterized by its upright, outwardly spreading and mounded plant habit; strong and vigorous growth habit; relatively large leaves; freely flowering habit; and large lacecap-type inflorescences with light violet blue-colored fertile flowers and white-colored sterile flowers. It has stunning clusters of blue flowers surrounded by light blue to white florets. Blue Bunny blooms every summer, even if you cut it back to the ground before the season. The blue color of its flowers are unaffected by aluminum, acidic or alkaline pH in the soil.
It originated from a cross-pollination in 2000 of two unnamed seedling selections of Hydrangea involucrate
