The garden gets exciting with this hydrangea and its large light blue lacecap heads on long stems. Blue Billow is very free-flowering in filtered shade or wooded areas. Strong stems with coarse colorful leaves make it a stunning addition to your shady garden. It is one of the hardiest and compact growing of the Serratas with fantastic fall color. We believe that this hydrangea originally came from the Dupont family gardens in Philadelphia.
