Libelle is a remarkable low profiled hydrangea with glossy, green, and tapered leaves that provide a background for the snow white blooms with cupped petals. These sterile flowers are loosely arranged among the multi-colored fertile center flowers. This highly valued white lacecap makes a statement of its own, especially when used in conjunction with hydrangeas of contrasting colors. Bred in 1964 by Federal Research Institute for Horticulture.
