I suspect this is a renamed variety that is closely related to the Mariesii family of hydrangeas (Blue Wave, Lemon Wave, Lilacina, Perfecta, White Wave) with its humongous blooms, darkest green leaves and stunning summer show. Sterile flowers start out white but fade to blue in acidic soils and pink in more neutral soils. Fertile florets are pink, purle or blue, again depending on the pH of the soil. Blooms come later in the season. Longest tapered leaves are a graceful reminder that this is a must have for lacecap lovers.
