'Wim Rutten' Blue Bunny™ - This dwarf plant is ideal for small gardens or containers. The summer lacecap inflorescences have pale blue to white sterile flowers and deeper blue fertile flowers. Unlike other hydrangeas, the plant continues to produce new flowers into the fall, so there is always fresh color on the plant.
